12128. As used in this chapter, the "drop safety requirement for
handguns" means that at the conclusion of the firing requirements for
handguns described in Section 12127, 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 primed case (no powder or projectile) shall be inserted into the
chamber. For pistols, 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 pistols and revolvers, 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 design of a pistol is such 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.
The following six drops shall be performed:
(a) Normal firing position with barrel horizontal.
(b) Upside down with barrel horizontal.
(c) On grip with barrel vertical.
(d) On muzzle with barrel vertical.
(e) On either side with barrel horizontal.
(f) If there is an exposed hammer or striker, on the rearmost
point of that device, otherwise on the rearmost point of the weapon.
The primer shall be examined for indentations after each drop. If
indentations are present, a fresh primed case shall be used for the
The handgun shall pass this test if each of the three test guns
does not fire the primer.
