(b) A signal pistol for launching an aerial flare not under paragraph (a) of this section may have any chamber and bore dimensions if they are not the dimensions for a conventional round of ammunition.

§160.028-3   Materials, workmanship, construction, and performance requirements.

(a) Materials. The materials used in signal pistols shall conform strictly to the specifications and drawings submitted by the manufacturer and approved by the Commandant. In general, all parts shall be corrosion-resistant or properly protected against corrosion. The ejection mechanism shall be of material possessing excellent wearing qualities.

(b) Workmanship. Signal pistols shall be of first class workmanship and shall be free from imperfections of manufacture affecting their serviceability or appearance.

(c) Construction and performance requirements. (Pistols intended for signals meeting Subpart 160.024). Signal pistols shall be of rugged construction and shall operate satisfactorily in firing and ejecting pistol-projected parachute red flare distress signals of the type covered by Subpart 160.024. The ejection mechanism shall be of sturdy design capable of withstanding rough and repeated usage. The overall size and weight of signal pistols should be kept to a minimum consistent with adequate strength and safety. When the pistol is cocked and the trigger is pulled, the firing pin shall project between 1.52 mm and 2.54 mm (0.060 in. and 0.100 in.) beyond the face plate of the frame. When the barrel is locked in the firing position, the barrel chamber shall be not more than 0.25 mm (0.010 in.) from the face plate of the frame.

§160.028-4   Approval and production tests.

(a) Approval test. An independent laboratory accepted by the Commandant under §159.010 of this chapter must test three pistols in accordance with the operational test in paragraph (c) of this section.

(b) Production inspections and tests. Production inspections and tests of each pistol must be conducted under the procedures in §159.007 of this chapter. Each pistol which passes the production inspections and tests must be stamped with the letters “P.T.” Each pistol which fails the test must not be represented as meeting this subpart or as being approved by the Coast Guard.

(1) Inspections and tests by the manufacturer. The manufacturer's quality control procedures must include the inspection of the pistols during production, and inspection of the finished pistols, to determine that the pistols are being produced in accordance with the approved plans. Each pistol must be tested in accordance with the operational test in paragraph (c) of this section, except that checking of the chamber and bore dimensions is not required.

(2) Inspections and tests by an independent laboratory. An independent laboratory accepted by the Commandant under §159.010 of this Chapter must inspect and test three pistols at least one each year. The inspection must determine that the pistols are being produced in accordance with the approved plans. The test must be in accordance with paragraph (c) of this section.

(c) Operational test. The operational test must be conducted as follows:

(1) Check the chamber and bore dimensions of the pistol.

(2) Fire a dummy cartridge simulating a normal signal in size and weight, but with a charge double the normal charge.

(3) Fire a normal signal.
