Section II. DESCRIPTION AND DATA

4. Description

a. The caliber .45 automatic pistol,

M1911A1 (figs. 1 and 2) is a recoil-oper-

ated, magazine-fed, self-loading hand

weapon. It contains an inertia-type firing

pm that makes it impossible for the firing

pin to discharge or touch the primer, ex-

cept on receiving the impact of the ham-

mer. The action of the recoil springforces

the slide forward, feeding a live cartridge

from the magazine into the chamber. The

weapon is now ready to fire again.

b. The pistol is designed to fire caliber

.45 cartridge ball ammunition and the

magazine holds seven cartridges. The

upper cartridge is stripped from the mag-

azine and forced into the chamber by the

forward motion of the slide. The pistol

will fire once at each squeeze of the trig-

ger and when the last cartridge, in the

magazine, has beenfired the slide remains

open. The rate of fire is limited only by

the ability of the operator to insert the

magazine and to squeeze the trigger.

C. The M1911 pistols still available in

the field will be maintainedusing M1911Al

repair parts.

d. For convenience of maintenance and

replacement of repair parts., the M191lAl

pistol is i6-ivided into groups and compo-

nents as indicated in figure 3.
