NLECTC Tests Autoloading Pistols for Law Enforcement Use

A law enforcement officer's firearm is one of the most visible symbols of the
officer's authority. It is also a constant reminder of the unique responsibility that
a police officer has--to use deadly force when needed to protect his or her life
or the lives of citizens. A firearm that does not work reliably can result in
serious injury or death to the officer and possibly to bystanders. 

The National Institute of Justice (NIJ), through its Office of Law Enforcement
Standards (OLES), has developed voluntary minimum performance standards
for revolvers, autoloading pistols, and shotguns for police use. During the
mid-1980s, NIJ sponsored a series of tests in each of these three categories of
firearms and published the results as Equipment Performance Reports (EPRs).

Recognizing that the vast majority of law enforcement agencies today use
autoloading pistols as their issued duty weapon, NIJ, through its National Law
Enforcement and Corrections Technology Center (NLECTC) system, recently
performed another series of tests for autoloading pistols. The tests were
performed in accordance with the requirements of the recently revised version
of Autoloading Pistols for Police Officers (NIJ Standard-0112.03, Revision A).

This standard establishes performance requirements and test methods for
pistols used by law enforcement officers as their duty weapon and is intended
for use in assessing the acceptability of new or reissue[1] autoloading pistols. It
does not address specific safety devices, full or partial magazine release, pistol
shot group size, accuracy, or sights. Nor does it address service life (endurance
testing).

The standard is a general revision of and supersedes NIJ Standard-0112.02,
dated January 1995, and addresses new pistol designs, calibers, revised
procedures for verifying headspace, and general revision of the testing
procedures. NIJ Standard-0112.03 replaces the 10mm with the .357 SIG
caliber. Revision A of NIJ Standard-0112.03, issued in July 1999, clarifies
procedures for test methods and incorporates data collection and revised
reporting requirements.

The requirements of NIJ Standard-0112.03 (Revision A) are very stringent, as
they represent the level of performance required for a pistol that is fully capable
of service use under the demanding conditions and environments in which law
enforcement officers work. NLECTC testing requires that the samples tested
be combat ready directly "out of the box." In the interest of safety, however, it
is recommended that when an agency purchases new pistols, each pistol be
examined by a qualified armorer and judged to be combat ready before being
issued.

To comply with the requirements of the standard, two representative samples of
a pistol model must successfully pass all informational, functional, and test
requirements defined in the standard. These requirements are listed in table 1
(page 2). There are no provisions for partial compliance with the standard.
However, a model that fails only one of the testing requirements may be
submitted for retesting to that specific test. But the manufacturer must provide a
written explanation indicating why--in the manufacturer's opinion--the model
failed that portion of the test, as well as what steps will be taken to correct the
problem. Once the model passes the retest, the model will be found to comply
with the requirements of the standard. Any significant change in the construction
of the pistol by the manufacturer requires that it be submitted under a new
model designation and tested to all of the requirements of the standard. 

NIJ Standard-0112.03 (Revision A) addresses four calibers of weapons: 9mm
Luger, .357 SIG, .40 S&W, and .45 ACP. These are the four calibers that are
commonly chosen by law enforcement agencies as their primary duty weapon.
NLECTC contacted the major manufacturers of autoloading pistols for police
use and requested that they provide pistols for testing. Manufacturers were
asked to limit their submissions to models in these four calibers. Eight
manufacturers (Colt, Glock, Kahr Arms, Kimber, Ruger, SIG Arms, Smith &
Wesson, and Taurus) agreed to submit a total of 23 pistol models for testing.
The models and calibers tested are detailed in table 2.

NLECTC issued subcontracts to two independent testing laboratories (H.P.
White Laboratory, Inc., Street, Maryland; and United States Test Laboratory,
LLC, Wichita, Kansas) to perform this testing. Both laboratories submitted
proposals that were evaluated by NIJ, OLES, and NLECTC. In addition, both
laboratories successfully demonstrated their capabilities to perform testing in
accordance with NIJ Standard-0112.03 (Revision A) by conducting
preliminary tests on two pistols of the same model, which were provided by
NLECTC.

Testing was performed between August and October of 1999. Test results
showed that 17 of the 23 pistol models complied with the standard. Three
models failed to comply with two or more of the critical test areas of the
standard and were therefore not eligible for retesting. Two models failed one of
the test requirements. However, each model was eligible for limited retesting in
their respective areas of failure. Both models failed to comply upon retesting.
Another model failed one of the test requirements (dimensional); the
manufacturer elected not to submit the model for retesting. A summary of the
test results can be found in table 3.

An Equipment Performance Report detailing the complete test results will be
available in early 2000. To receive a copy of this EPR, call NLECTC at 800-
248-2742 or 301-519-5060, or write to P.O. Box 1160, Rockville, MD
20849-1160. The EPR also will be available for downloading from NLECTC's
Internet site, JUSTNET, at www.nlectc.org.

Endnote

1. All pistols must be examined and reconditioned as necessary by a trained
armorer or gunsmith prior to reissue.

--------------------------------

Definitions 

Double action: A mode of operation that permits a single pull of the trigger to
cock and fire the pistol. (See single action and striker fire action.)

Headspace: The distance between the closed breech face of the firearm and the
surface of the chamber on which the cartridge case seats.

Malfunction: Failure to feed, fire, or eject a round or failure to accept or eject a
magazine; or failure of the slide to remain open after the last round has been
fired.

Model: The manufacturer's designation which uniquely identifies a specific
design of autoloading pistol.

Single action: A mode of operation that uses the trigger to fire the pistol only.
(See double action.)

Striker fire action: A pistol design that employs an internal striker mechanism to
detonate the primer. In operation, the pistol is normally in a partially cocked
condition. Pulling the trigger completes cocking the action and then releases the
striker mechanism to fire the pistol.

Trigger pull: The force that must be applied to the trigger to fire the pistol.

Table 1 

The test

To satisfy the requirements of NIJ Standard-0112.03 (Revision A), both
sample pistols of the same manufacturer and model must pass all of the
following requirements and tests:

1. User Information. At a minimum, the manufacturer must include with each
pistol information detailing instructions for field disassembly/assembly and
diagram(s) identifying all parts; cleaning instructions; a description of each safety
feature designed into the pistol; a statement on ammunition known to be beyond
the design limits of the pistol; and how a parts list may be obtained.

Manufacturers may supply any other information that they believe may be
needed by the user for proper and safe operation of their handgun.

2. Visual Inspection. The pistol must meet the following visual inspection
requirements:

a. Hammer Travel. In the single action mode, if present, the hammer shall have
sufficient over-travel to assure achievement of the full cocked position.

b. Particles. There shall be no loose chips, shavings, or filings in the pistol.

c. Surface. The pistol shall have no chips, scratches, or burrs. There shall be no
sharp edges or corners that could cut the shooter's hand while firing or during
manual cycling of the pistol.

3. Dimensional Requirements.

a. Barrel Bore Dimensions. The barrel bore diameter shall be in accordance
with Sporting Arms and Ammunition Manufacturers Institute (SAAMI)
Standards for the caliber for which the pistol is chambered.

b. Headspace. The headspace shall be in accordance with SAAMI Standards
for the caliber for which the pistol is chambered.

4. Functional Requirements.

a. Action. The slide shall operate smoothly without binding or sticking when
operated by hand or during firing tests.

b. Ejection. The ejection mechanism shall eject cases without hangup and
without hitting the shooter during the ejection test or the firing tests, except as
provided in Sections 4.6 and 4.8.

c. Trigger.

--1. The single action trigger pull force shall be not less than 13 N (3 lbf) nor
more than 36 N (8 lbf) when tested.*

--2. The double action trigger pull force shall be no more than 80 N (18 lbf)
when tested.*

--3. For a pistol employing a striker fire mechanism, the trigger pull force shall
be not less than 22 N (5 lbf) nor more than 67 N (15 lbf) when tested.*

d. Hammer. When tested, the hammer shall operate smoothly without binding
and shall not release under an applied load of 46 N +- 1 N (10 lbf +- 1/4 lbf).

e. Safety Features. The pistol shall have one or more design features to prevent
inadvertent firing. Active (user activated) safety devices, if provided, shall be
designed so that the pistol can be made fire-ready by releasing the safety(s)
with the shooting hand. The pistol shall not fire when tested with the safety
feature(s) engaged.

f. Magazine. The magazine shall have a capacity of six rounds, minimum, and
shall be capable of being released without removing the shooting hand from the
pistol.

5. Model Qualification Firing Requirement. When tested in accordance with
Section 5.6.1, the pistol shall fire 600 rounds of ammunition with no structural
or mechanical failures and no more than five malfunctions. Of the five allowable
malfunctions, no more than three shall be firing malfunctions not attributable to
faulty ammunition.

6. Drop Safety Requirement. The pistol is dropped from a height of 4 feet onto
a 1-inch-thick rubber mat, backed by concrete. The pistol shall not fire
(cartridge with a live primer, but no bullet) during the drop test. The following
seven drops are required for each of the pistols constituting the sample:

--1. Normal firing position; barrel horizontal.

--2. Upside down; barrel horizontal.

--3. On grip; barrel vertical.

--4. On muzzle; barrel vertical.

--5. On left side; barrel horizontal.

--6. On right side; barrel horizontal.

--7. If there is an exposed hammer or striker, on the rearmost point of that
device; otherwise on the rearmost point of the pistol. Alternately, a weight
equivalent to that of the pistol may be dropped onto the rearmost point.

Firing of the primer on any drop constitutes failure of the test.

7. Drop Function Requirement. After completing the drops specified in the
drop safety test, examine the pistols for damage and note any cracks, chips, or
other visible damage. For those pistols that passed the drop safety test without
structural damage or damage that will affect the safe and proper functioning of
the pistol, insert a fully loaded magazine, chamber a round, and point the pistol
into a bullet trap or other suitable device. Fire until the ammunition has been
expended. Release the magazine (note any sticking or binding), reload, and
repeat until 20 rounds have been fired. Note any misfires or malfunctions. If
there are more than three malfunctions, repeat the 20-round firing test. If there
are no more than three malfunctions during the repeat firing test, the pistol meets
the requirements of this test.

*N, the metric unit or force, is equal to 0.2248 lbf. For the purpose of this
standard all conversions from Newton to pound-force for required values and
measurements have been rounded to the nearest 1/4 lbf.
