Title 9 Part 482

As used in this Part, the following terms shall mean and include:

In the alternative, he shall make available a completely assembled firearm manufactured in compliance with said certificate of compliance. Such samples or firearm shall be made available on request of the superintendent at such time as he may deem necessary.

All firearms manufactured or assembled pursuant to this Part shall meet the following material and parts specifications:

A basic structural component shall not be made of any material having a melting point (liquids) of less than 1,000 degrees Fahrenheit, and any material having an ultimate tensile strength of less than 55,000 pounds per square inch, and no less than eight percent minimum elongation in accordance with standardized metallurgical testing procedures.

After firing a proof cartridge, on visual examination, the barrel shall be free of cracks, bulges or splits.

After firing a proof cartridge, on visual examination each chamber shall be free of cracks, bulges or splits. Cylinder stop notches (bolt notches) shall be formed to ensure positive engagement of the cylinder stop at each position aligned with the bore.

After firing a proof cartridge, on visual examination, the slide material shall be free of cracks, bulges or splits; and the slide shall function throughout its full range of travel on the receiver (frame) guideways.

After firing a proof cartridge, on visual examination, the cylinder-frame or receiver shall be free of cracks, bulges or splits.

The barrel/cylinder gap is the space between the front face of the cylinder and the rear breech face of the barrel, across which the bullet passes upon firing. After firing a proof cartridge, the barrel/cylinder gap for all calibers shall be no greater than.010 inch, measured at each firing position.

The chamber diameter shall be no greater than.005 inch in excess of the minimum chamber diameters listed in Appendix K-1.

Whenever a firearm model shall be tested pursuant to this Part, it shall be subjected to the following tests:

This test shall consist of the firing of one proof cartridge in each chamber. Each proof cartridge case shall be visually examined after firing to ensure there are no splits or other defects indicating firearm failure.

This test shall consist of firing 1,000 rounds of commercial ammunition. Failure shall not exceed the number listed as permitted in Appendix K-2. Firing shall be in series of not more than 500 rounds. The sample shall be cleaned and lubricated at least once during each series. The safety shall be tested at the conclusion of the test to determine that it functions as intended. Malfunctions caused by failure to clean and lubricate, or by defective ammunition, shall not be counted against the sample.

The safety device on a pistol or revolver (single- or double-action) with an exposed hammer must withstand the impact of a weight equal to the weight of the firearm dropping from a distance of 36 inches in a line parallel to the barrel upon the rear of the hammer spur, a total of five times. Breakage or deformation which renders further firing impossible and which is not accompanied by discharge is considered satisfactory performance. This test is to be performed after the successful conclusion of the endurance test.

The provisions of this Part shall become effective on April 1, 1976.
