As used in this part, the “drop safety requirement for handguns” means that at the conclusion of the firing requirements for handguns described in
Section 31905, the same certified independent testing laboratory shall subject the same three handguns
of the make and model for which certification is sought, to the following test:
(a) A primed case (no powder or projectile) shall be inserted into the chamber. For a pistol, the slide shall be released, allowing it to move forward under the
impetus of the recoil spring, and an empty magazine shall be inserted. For both a pistol and a revolver, the weapon shall be placed in a drop fixture capable
of dropping the pistol from a drop height of 1m + 1cm (39.4 + 0.4 in.) onto the largest
side of a slab of solid concrete having minimum dimensions of 7.5 x 15 x 15 cm (3
x 6 x 6 in.). The drop distance shall be measured from the lowermost portion of the weapon to
the top surface of the slab. The weapon shall be dropped from a fixture and not from the hand. The weapon shall be dropped in the condition that it would be in if it were dropped
from a hand (cocked with no manual safety applied). If the pistol is designed so that upon leaving the hand a “safety” is automatically applied by the pistol, this feature shall not be defeated. An approved drop fixture is a short piece of string with the weapon attached at
one end and the other end held in an air vise until the drop is initiated.
(b) The following six drops shall be performed:
(1) Normal firing position with barrel horizontal.
(2) Upside down with barrel horizontal.
(3) On grip with barrel vertical.
(4) On muzzle with barrel vertical.
(5) On either side with barrel horizontal.
(6) If there is an exposed hammer or striker, on the rearmost point of that device,
otherwise on the rearmost point of the weapon.
(c) The primer shall be examined for indentations after each drop. If indentations are present, a fresh primed case shall be used for the next drop.
(d) The handgun shall pass this test if each of the three test guns does not fire
