The Evolution of Law Enforcement Firearms Training Standards

Article By: Leo H.

In retirement, I find I am often contemplating things that probably do not really require consideration. There is a possibility I have been doing this my entire life, as I have been called a “purveyor of useless facts” on various occasions. At any rate, I recently found myself wondering about the evolution of law enforcement firearms training standards, spending considerable time roaming the internet in search of data. I apologize for the length of this post, as I fell down many rabbit holes during my journey and feel compelled to share.

At its heart, this is really the story of a pendulum swinging between two competing priorities -precision and speed -with each swing driven by some real-world event that exposed the cost of getting the balance wrong. I’ll walk through that swing chronologically, from the Old West to modern Georgia law enforcement, before landing on where I think that pendulum should rest today. Along the way, watch the targets themselves: their shapes and scoring systems changed dramatically -circles, silhouettes, elliptical rings, anatomical boxes, but the actual size of the highest-value zone has stayed remarkably consistent across more than a century of otherwise radical redesign.

The Old West

I first stopped in the Old West, attempting to find documentation on the training or standards established for the first town marshals and sheriffs. During that time, most East Coast law enforcement agencies did not begin issuing weapons to their officers until the mid to late 1800s. Officers of that era were largely unarmed, as their primary function was reactionary rather than preventative. Townsfolk in the West, however, found they needed armed officers to control the drovers who shot up their towns on a regular basis. When seeking a lawman, the standard of the day seems to have been to seek out individuals whose reputation marked them as competent marksmen, hunters, or gunfighters who had personally honed their skills, requiring no additional training before employment. The fact that such employment required a personal ability that could be measured by a gunfight at any given moment was sufficient incentive to remain proficient in individual gun handling and marksmanship.

A good example of an Old West marshal hired based on reputation would be James Butler “Wild Bill” Hickok. His reputation for marksmanship and gunplay led to his being hired to tame towns others had no desire to police. His skills were self-taught and honed from childhood. He is said to have had a daily ritual of shooting and cleaning each of his weapons, with emphasis on speed, precision, and distance shooting. His targets commonly included playing cards (2.5″ x 3.5″), fruit cans (4″ x 5″), dimes, and other such objects. While his ruthless enforcement methodology would certainly not be welcome today, his recognition of the need for adequate marksmanship ability, and the related need for continued training, should be considered by anyone who may find themselves in need of defensive handgun skills.

The City of Baltimore Police Department is credited with being the first to arm its officers. In 1857, the city purchased two hundred handguns, which were issued, without training, to its officers. Two months later, they were involved in their first shootout, in which the Deputy Marshal and several residents were shot by responding officers. In an open letter to the Police Board of Commissioners, the Mayor wrote that the untrained and unpracticed police department posed a far greater risk to the innocent citizens of Baltimore than the actual criminals they were trying to catch. He demanded a compulsory marksmanship and target practice program be immediately implemented for every officer. In 1895, Baltimore conducted its first structured pistol practice, where approximately 80% of officers were found to shoot with “reasonable accuracy” when firing an untimed course of fire at military rifle targets from ten to fifteen yards. Formal training of its personnel did not begin until 1913, with the opening of the Baltimore Police Department School of Instruction.

The Civil War Era

During the Civil War, most able-bodied men from both sides found themselves enlisted in the military. Many police officers were off at war, and worrying about training whoever remained at home in marksmanship fundamentals was not a consideration. The Union Army utilized a selection process for its elite rifle sharpshooters called the “Inches from the Center” test. This appears to be one of the first tests designed to measure individual shooting proficiency, requiring the soldier attempting to “qualify” for selection to fire ten shots into a ten-inch target from 200 yards. To be considered for selection, most of their shots could average no more than three inches from center. The Confederate Army, by contrast, had its candidates fire at small blocks of wood or knots on a tree at varying distances -you either hit the target, or you didn’t. Thus, two differing methods of measuring skill were born: one based on percentages, the other on a hit-or-miss philosophy.

While officers, cavalry soldiers, and artillerymen were often armed with handguns, most had never fired their weapon prior to engaging in combat. This lack of training was due primarily to a shortage of ammunition on both sides. The military did not prioritize handgun training because revolvers were viewed strictly as short-range, defensive weapons. Combat accuracy for these revolvers was found within the range of fifteen to twenty-five yards, though an accomplished shooter might be capable of hitting a target as far as fifty yards. However, there existed no proficiency standard of any kind for either the military or law enforcement during this time frame.

Standardizing Military Marksmanship

Following the Civil War, the consensus was that soldiers from both sides of the battlefield had been notoriously poor shots. As the US Army moved toward professionalism, it became apparent that a marksmanship program would need to be developed, with standards of proficiency required to develop and recognize individual skill. As the rifle was the primary weapon of the infantry, program development centered on its capability at distances of 200 yards and greater, with the bullseye of the Target-A measuring twenty-two inches in height and eighteen inches in width. The primary emphasis of training at this point was to teach soldiers to hit a body-sized target out to about 300 yards; if a soldier proved capable at that distance, the next phase of training extended it to 1,000 yards (1879–1885).

In 1885, the Army again revised its target design, and an eight-inch concentric ring became the “bullseye” for which all shooters hoping to achieve the ranking of expert aimed. Also in 1885, the American Standard Target, with an eight-inch bullseye, was established for use in 200-yard off-hand rifle shooting in competitive matches hosted by the National Rifle Association (NRA). As competitive interest in handgun marksmanship gained momentum, this target was scaled down to a 1/12th version used for fifty-yard precision handgun matches (standing, one-handed firing). Today, the NRA B-8 target is a direct, modified descendant of the 1885 American Standard design.

New York City and Theodore Roosevelt

In 1896, while serving as President of the New York City Board of Police Commissioners, Theodore Roosevelt pioneered the department’s first training, practice, and qualification protocols. The department created the School of Police Pistol Practice, built an indoor range, and began a program intended to enhance personal handgun proficiency. Designed by an officer who was a highly successful competitive target shooter, the program consisted of three phases:

1. A baseline evaluation where each officer fired 5 to 10 shots at 10 to 20 yards. This course was intended to answer the question, “Can they shoot straight?” and only required the capability of hitting a large body-sized target (six feet tall by four feet wide with a five-inch aiming circle).
2. Officers were then required to attend regular structured training where they had to demonstrate improvement on a qualification course using the scaled-down version of the American Standard Target (3.04-inch X-ring), firing a course at 10 or 15 yards consisting of 10 rounds, and scoring a minimum of 60% accuracy.
3. Individual shooting scores were tied to merit increases in pay and promotion, reflecting responsibility and accountability.

The standard for the next thirty years remained the expectation that 60% of all non-timed, one-handed fire would fall within a 7.44-inch circular scoring zone.

An article written by Frank J. Kahrs in 1916 for the NRA magazine Arms and the Man stressed that police officers should receive a systematic program of firearms instruction at the start of their careers, followed by monthly range training thereafter. In 1920, the NRA surveyed agencies across the nation serving populations of 25,000 or more, and found only three cities -New York, Chicago, and Berkeley -that provided formal, departmentally mandated firearms marksmanship training to their officers. As a result of that survey, in 1926 the NRA and the Army’s National Board for the Promotion of Rifle Practice established a Special Police School at Camp Perry, Ohio, to train officers nationwide. Cardboard silhouette targets (the NRA Colt Silhouette Target) were introduced for “combat” training, while the precision marksmanship world continued using the American Standard Target for slow-fire practice.

The Bureau of Investigation Becomes the FBI

In 1908, President Theodore Roosevelt created an investigative force that was later named the Bureau of Investigation (BOI) to crack down on government corruption, land fraud, and corporate crime. These agents had no statutory authority to carry firearms or make arrests; legally, they could carry weapons only under the same rules as any civilian, and doing so required only the informal approval of a supervisor. Most agents carried a weapon anyway, but there was no formal policy, training program, or qualification standard during this period. Just as in the Old West, becoming proficient -and staying that way -was the responsibility of the individual agent.

That changed in 1934, when a package of federal crime bills gave Bureau agents statutory authority to carry firearms and make arrests, and Congress funded formal weapons issue and mandatory training for the first time. The Bureau was officially renamed the Federal Bureau of Investigation (FBI) the following year, in 1935. ^[1] Agents were now required to attend mandatory training and demonstrate proficiency by successfully qualifying on strict courses of fire.

Early law enforcement courses predominantly used the Colt Silhouette Target, with K (Kill) and D (Disable) scoring areas, rather than the circular scoring rings used by competitors. J. Edgar Hoover worked with legendary firearms expert Elmer Keith and FBI instructors to develop the Practical Pistol Course (PPC) in the 1930s. The course was intended to simulate real-life combat scenarios by requiring agents to shoot from various distances and positions, including kneeling, barricaded, and moving-target engagements.

In 1935, the FBI National Academy was established, where standardized, scientifically grounded training for local police was taught to high-level officers from across the nation. This allowed the FBI to centralize firearms instruction and train local departments in advanced combat shooting techniques as these officers returned home. Today, the FBI remains at the forefront of firearms program design and instructional development through its own field programs and its impact at the federal level. However, many local agencies receive the bulk of their instructional certifications through NRA programs or other POST-recognized training, which are usually more accessible to line-level officers than federal-level instruction. Additional instructor-level training is now also available at the various Federal Law Enforcement Training Center (FLETC) sites and their field-level programs.

Target Evolution: From the B-21 to the B-27

In the mid-20th century, the NRA modified the Colt Silhouette to standardize police training and competitive matches, giving rise to the B-21 target – “B” denoting the NRA’s pistol target series ^[4]. As the target was adopted by the FBI, it became widely used by progressive departments of the era, until the introduction of the B-27 in 1962. The B-21 used large scoring areas rated for combat effectiveness; the B-27 brought back scoring rings, making it more difficult to obtain high scores in competition. The highest point value on the B-21 is in the center-chest area, a circle 7.5 to 8 inches in diameter. The highest point value on the B-27 is the X-ring, an elliptical shape 2 inches by 3 inches, surrounded by the 10-ring, which measures 4 inches by 6 inches. The X on the B-27 is placed in the center of the paper target itself, rather than at a point of tactical significance on the silhouette. Notably, that B-21 center-chest circle -7.5 to 8 inches -is nearly identical in size to the 7.44-inch zone the NYPD had settled on some thirty years earlier; the shape of the target changed completely, but the size of the zone you actually had to hit barely moved.

The B-27’s design was based on merging the scoring zones of the International Shooting Sport Federation (ISSF) target with the Colt Silhouette. To fit the ISSF’s circular scoring rings inside the humanoid silhouette, the rings had to be stretched into ellipses -so the 4-inch circular center ring of the competitive target became a 4-inch by 6-inch elliptical ring within the silhouette. The target’s overall size was based on the target-frame dimensions most commonly used on police ranges in the 1960s, rather than on human proportions.

Standardized law enforcement firearms instruction began on a large scale in 1960, when the NRA Law Enforcement Division introduced its first firearms instructor and training certification schools. From 1960 to 1962, these schools used the B-21 target; focus shifted to the new B-27 in 1962 as the NRA launched its Police Pistol Combat (PPC) competitive format and redesigned its instructor course around the new PPC standards. The 60-round version of the 1962 NRA instructor course was strict: it awarded no points for shots outside the seven-ring, and was fired at 7, 25, and 50 yards, with attendees required to score at least 80% to graduate. NRA courses still use a version of the B-27 today, officially designated the B-27E -the scoring lines remain the same; only the overall paper size differs. Scaled-down versions are available as the B-29 and B-34.

In 2007, the NRA introduced the Excellence-In-Combat (EIC) target, designed specifically for Tactical Police Competition (TPC) and also used in its tactical shooting instructor courses. This target moves away from precision-based scoring toward an anatomical system, with the highest values concentrated over true human vital areas (high chest, heart, and center head). The head box is a 4-inch by 6-inch rectangle with slightly rounded corners; the thoracic cavity is an 8-inch by 12-inch rectangle positioned squarely in the center of the chest. In tactical courses, hits outside these high-value areas result in reduced scoring or penalties.

The FBI “Q” Target

Through the mid-1960s, and with heavy NRA influence, the law enforcement firearms community focused predominantly on accuracy training, with visual focus centered on the X-ring for the highest possible ranking. In the late 1960s, the FBI designed a new “Q” target intended to move away from military-style marksmanship toward real-world application. The concern was that agents were spending too much time searching for a small, specific aim point during the stress of an actual gunfight, putting them behind the time curve that can determine the winner of a gunfight. Moving away from circular targets and back toward one that reflected anatomical realism seemed the better option. The “Q” target roughly simulates the head and upper torso of the human body, giving it the rough look of an upright physical threat.

While traditional scoring rewarded rounds landing close to the center of the target, the original “Q” was designed as a hit-or-miss target, intended to teach agents to make fast, combat-effective hits rather than take extra time chasing a higher “X” count. Over time, the target evolved into a narrower design that forces shooters to account for suspects wearing body armor or using tactical cover (QIT-97, QIT-99). The original “Q” target has an upper-torso width of 11.5 to 12 inches, while the QIT-99 measures 8 to 10 inches and stands about 2 inches shorter than the “Q.” The “Q” has no internal scoring boxes, while the QIT-99 allows high-value precision hits within a head box (a 3-inch square) and an upper thoracic box (4 inches by 6.5 inches). Today, FBI training has moved away from the “aim small, miss small” philosophy toward the training mantra, “Be fast, be accurate, and hit your target first.” Regardless of how a target is designed, it’s worth remembering that none of them are meant to accurately replicate a real human being -they are designed to mathematically measure a standard of control.

IPSC and the Rise of Practical Shooting

Next in the evolution of defensive pistolcraft is the founding of the International Practical Shooting Confederation (IPSC) in 1976. While originally intended to develop defensive handgun skills, it has since evolved into more of a pure sport than a reflection of its original purpose. Even so, many of the weapon and equipment designs, modifications, and shooting techniques developed within IPSC have found their way into mainstream law enforcement firearms training.

The IPSC motto, Diligentia, Vis, Celeritas -or DVC -as articulated by Col. Jeff Cooper (the organization’s first president, and widely regarded as the father of the “Modern Technique” of handgun shooting), remains the foundational philosophy of the sport. Diligentia signifies the need for accuracy, evaluated through precise shot placement. Vis stands for power, measured by bullet weight and velocity, on the belief that this confers a relative ballistic benefit in a gunfight. Celeritas is speed, since accurate and fast shots are generally the determining factors in surviving a deadly encounter involving gunplay. Match winners are determined using a method called Comstock scoring, named for its inventor, Walt Comstock ^[2], in which a Hit Factor is calculated by dividing a shooter’s total points (target values are set by the power of the caliber and load) by the elapsed time to fire the course. The shooter with the highest Hit Factor wins.

The IPSC Classic target is a hexagonal, non-humanoid shape, while the IPSC Metric target is derived from human torso and head proportions to simulate a real-world defensive encounter. The A-Zone (highest value) on the Metric target measures approximately 6 inches by 11 inches for the torso and 4 inches by 2 inches for the head. IPSC is a competitive organization and does not offer law enforcement instructor certifications of its own; even so, many agency training programs are heavily influenced by the techniques used by top-level competitors, based on their perceived real-world relevance. Just as the instructor rosters of early law enforcement agencies were full of NRA bullseye shooters, today’s rosters are filled with defensive-pistol competitors.

IDPA: A Return to Defensive Fundamentals

As IPSC evolved away from its defensive-pistol roots, a prominent group of firearms industry experts and tactical instructors formed the International Defensive Pistol Association (IDPA) in the mid-1990s. Their intent was to move away from an environment where equipment (“race guns”) largely determined who the top shooters would be, and toward one where courses of fire were built around “real-world” self-defense scenarios rather than the purely athletic “run and gun” obstacle courses IPSC had become. The focus centered on individual shooting skill and defensive proficiency, and there is much within the organization that carries direct street relevance for a working officer. While many firearms instructors do compete in IDPA matches, IDPA -like IPSC -does not offer law enforcement instructor certification courses.

The IDPA target is similar in shape to the IPSC Metric humanoid design; the primary difference lies in the scoring zones. Where IPSC awards specific numerical points based on shot placement, IDPA instead adds time for shots landing outside its “Down Zero” area in the head and torso (a 4-inch circle in the head, an 8-inch circle in the torso). Using the Vickers Count scoring method -named for firearms instructor and IDPA co-founder Larry Vickers ^[3] -shooters are ranked by their ability to shoot accurately in the fastest possible time; slow, accurate shots alone will not win a match. Once again, note the size: an 8-inch torso circle and a 4-inch head circle -right in line with every other high-value zone this essay has touched on, from the 1890s to today. Time penalties are also assessed for hits on non-threat targets, procedural errors, rule infractions, unsportsmanlike conduct, and cheating. Accuracy still reigns dropping a single shot into the -3 zone adds three seconds to a shooter’s overall time, enough to drop them out of contention almost immediately. This may be a more effective model for scoring law enforcement qualification, since it pushes the shooter toward fast, accurate hits rather than simply firing rounds and hoping for a passing score.

Georgia Law Enforcement Training

In Georgia, Chatham County lays claim to the state’s first Office of the Sheriff, with peacekeeping responsibility beginning in 1732. The City of Savannah found the need for a group of “watchmen” to patrol the city at night in 1796, a role that was dissolved once the city formed an actual police department in 1854. Over the following decades, each of Georgia’s largest cities established some form of law enforcement agency. For the most part, officers received no formal firearms training and were simply expected to know how to safely and effectively use their weapons if the need arose. Atlanta built its first range and began training officers in the 1940s; Savannah PD began its formal training program in 1959; and the Chatham County Sheriff’s Office began structured training in the mid-1970s, following the creation of the Georgia Peace Officer Standards and Training Council (GPOSTC) in 1970.

The first Basic Law Enforcement Training Courses (BLETC) took place in 1971, with a 114-hour curriculum that included 16 hours of deadly-force training (covering applicable state and federal statute, liability issues, principles of marksmanship, live-fire training, and qualification). Ranges that permitted 50-yard shooting fired to that distance; those that did not reduced the qualification round count from 60 to 50 rounds and the maximum distance to 25 yards. Which course of fire each academy used to “qualify” its students was left to the individual academy director, with the standard being equivalency to whatever course the FBI used for its agents, or whatever the NRA required in its law enforcement classes. The accepted degree of accuracy was 70%.

Over the years, the BLETC curriculum has grown to a minimum of 810 hours, with 72 dedicated to some form of deadly-force training. The first standardized GPOSTC qualification course at the BLETC level was established in 1978 and has been revised three times since (2005, 2021, and 2025). Most agencies with a policy requiring annual proficiency demonstrations used the entry-level BLETC course for that purpose. In 2006, GPOSTC rules changed to require annual requalification for all certified officers who wished to retain their arrest powers, regardless of existing departmental policy. The wording of the rule is somewhat vague: Rule 464-5-.03.1 requires each officer to provide “a demonstration of proficiency in the safe and effective use of any agency issued firearm carried and/or used by the particular officer, to include a course of fire that meets or exceeds the minimum standard set forth in the basic training course for which an officer was initially trained and is currently employed.” This suggests an officer need only meet the standard of the course in place when they attended the BLETC, though most agencies use whatever the current course happens to be to satisfy the requirement.

The BLETC qualification course uses the SQT-A1 target, the only target GPOSTC recognizes for firearms qualification or requalification. The highest point value comes from hitting an 8-inch by 11-inch box in the upper torso or a 3-inch by 5-inch head box. A secondary version, the SQT-A1-RCSO (Richmond County Sheriff’s Office), adds a high-visibility six-inch by six-inch box centered within the standard torso box and a similarly colored 3-inch by 2-inch head box, intended to support more advanced training and tighter scoring. Georgia’s own entry-level standard, in other words, lines up almost exactly with the sizes we’ve seen throughout this whole history.

Most Georgia law enforcement instructors find the 2025 BLETC course relatively easy to pass. Its large scoring zones leave a wide margin for error; its lack of extended distance (maximum 15 yards) reduces the need for precision aiming; and its generous shot pacing (2 seconds per shot) encourages shooters to slow down for a better score rather than push for realistic gunfight speed. While the course may be an adequate way to evaluate entry-level skills in an academy setting, agency instructors should look well beyond this foundation when designing a departmental firearms program.

Where This Leaves Us

Looking back, law enforcement firearms training began with the modest goal of ensuring an officer entrusted with a handgun could, at minimum, hit a body-sized target from 10 to 15 yards, firing one-handed and under no time constraint. That standard moved quickly toward 50 yards, where an 8-inch circular target was used to measure expertise in both the military and the civilian competitive world. As weapon technology advanced, target design and time constraints both became considerations in measuring marksmanship. Inner rings were added within the original 8-inch “bullseye,” and a 3.36-inch 10-ring was established as the widest acceptable spread for an expert marksman at 50 yards in the slow-fire matches of the late 1800s. Accuracy was king, and most handgun training centered on the needs of the military or the competitive shooting world.

The early 1900s brought both the military and law enforcement around to the idea that a humanoid silhouette target would be a more valuable training tool. While a central “X” focus remained on these targets, it was generally accepted that a hit almost anywhere on the human body could kill or disable an adversary, and that philosophy was reflected in the scoring zones. Reality, however, showed that accurate shots were still needed to reliably end a threat’s ability to fight, so small scoring zones returned. From the 1920s and ’30s until the early 1960s, hitting the 4-inch by 6-inch 10-ring of the B-27 target was the goal of expert marksmen in both civilian and law enforcement circles. The 2-inch by 3-inch “X”-ring was the focus of the best of the best, which often required a specialized handgun, low-recoil ammunition, and efficient use of the allotted time to build a high “X” count. The superior marksmen of this era aimed to shoot tiny groups of shots into a large sheet of paper.

In the 1960s, the FBI began to recognize that taking the time to shoot small groups could be a liability in a gunfight. Training and qualification standards shifted away from precision accuracy toward combat-acceptable accuracy, as reflected in the FBI “Q” target. Situations and assignments still existed where precision was required to end a threat, and training time was still devoted accordingly. The mathematically designed “Q” scoring zones roughly correspond to human vital areas, and reducing the time allotted for hits in these zones more closely replicated an actual gunfight. Today, the FBI’s QIT-99 is roughly a third smaller than its predecessor, and numeric scoring is once again being used to measure proficiency, moving away from the pure hit-or-miss philosophy of earlier decades.

Law enforcement firearms training has also grown to include the use of cover, positional shooting, shooting on the move, and other techniques well beyond the stationary, one-handed shooting that was the mainstay in the beginning. However, as it becomes harder to find candidates willing to choose law enforcement as a profession, training and qualification standards are trending softer, to allow a broader base of applicants to successfully complete entry-level requirements. Consider, for example, that prior to 9/11, the Federal Air Marshal Service (FAMS) Tactical Pistol Course (TPC) was widely considered the most demanding law enforcement qualification in the profession. Requiring 90% accuracy, under compressed time limits, with most rounds fired from concealment, it was an extremely challenging course that few could master. The hiring surge required to staff the agency after 9/11 found that 70% of recruits attending the New Agent program could not qualify and were dropped from the program as a result. A more attainable standard was ultimately established to bring the academy attrition rate back down.

In Georgia, BLETC programs have moved shooting distance from 50 yards to 25 yards, and now to a 15-yard maximum, while firing stages use increasingly generous time frames. Perhaps we’re back at Teddy Roosevelt’s original standard -simply being satisfied that everyone is capable of hitting the target somewhere.

One pattern is hard to miss once you’ve traced it: the shape of the target has been reinvented again and again -circles, silhouettes, elliptical rings, anatomical boxes, but the size of the zone you actually had to hit to be considered proficient has barely budged. A 7.44-inch NYPD zone in the 1890s, a 7.5-to-8-inch B-21 zone, an 8-by-11-inch SQT-A1 box, an 8-inch IDPA down-zero circle -these are all, functionally, the same target wearing different clothes. That consistency tells me something the shifting target designs alone don’t: whatever the era, whatever the organization, the physical reality of what it takes to reliably stop a threat hasn’t actually changed. Only our appetite for how fast we ask someone to do it has.

And so, in my quest to better understand where defensive handgun standards were derived from -and what they should actually be -I’ve come to the conclusion that standards should reflect distances that are statistically relevant to real encounters, with the goal of hitting what you intend to hit as fast as you can. You should be able to place your shots within at least a 6-to-8-inch circle in a tactically appropriate area for combat-acceptable accuracy, or within a 3-inch circle where precision shots are called for -numbers that, as it turns out, this entire history already agrees with.

When choosing a target to train with, the NRA B-8 seems like a good choice: it’s easy to find, inexpensive, and provides a means of scoring if scoring is required. Use the full target to replicate the size of a human head viewed from the front or the upper thoracic region of a human torso; fold it in half to train for shots from the side. It doesn’t have to be complicated to be practical.
