BFunctional Inspection

(1) Check functioning of safety. Refer to paragraph 15c(l).

(2) Check functioning of grip safety. Refer to paragraph I5c(2).

(3) Check functioning of hammer or sear. Refer to paragraph 15c{3).

(4) Check functioning of disconnector. Refer to paragraph 15c{4).

(5) Upon completion of inspection, pistols will be properly cleaned and lubricated (paragraphs 19 and 23).

c. Trigger Pull Teft. Check the trigger pull using trigger pull measuring fixture (figs. 12 and 13) and in accordance with instructions indicated in (1) and (2) below:

(1) With the safety unlocked, rest the weight on the floor and hook the notched portion of the rod over the center portion of the trigger.

NOTE; Make certain the rod does not contact or rub any portion of the pistol and that rod and barrel arc pamllel. Empty magazine must he installed when checking trigger pull.

(2) Depress grip safety and carefully raise the weight from the floor. When using the 5 pound weight (minimum), the trigger should not release the hammer. When using the 6.5 pound weight (maximum), the trigger should release the hammer.

CAUTIONt A slow or steady lift must be utilized to assure a rnic and accurate check.

d. Correcting Trigger Pull.

(1) Trigger pull loo light.. This is evidence of a worn cocking notch on the hammer, worn or damaged scar or a weak helical compression housing spring. Examine the components for wear or damage. If tTigger pull cannot he corrected by stoning┬╗ replacc with new components as required.

(2) Trigger pull excessive. This is evidence of burs or surface irregularities on rhc hammer full'cock notch or scar. A helical housing spring rhar is damaged or too strong and/or interferences or binding between the mating surfaces of the pertinent parts within the receiver group are other probable causes. If the trigger pull cannot be corrected by stoning, replace with new components as required.

0) Creep m trigger. Creep is defined as a perceptible movement of the trigger after the slack has been taken up and before the hammer is released. It is caused by rough or uneven mating surfaces of the sear, hammer, and disconnector and also by unserviceable sear and ham* mcr pins. If the creep cannot be corrected by stoning, replacc with new components as required.

CAUTION* While stoning, critical dimensions should not be altered.

e. Hand Function Test.

(1) Place three dummy cartridges in magazine (fig. 52). Insert magazine in receiver group. Release slide stop. This action would cause barrel and slide group to move forward. At the same time, a dummy cartridge will be stripped fmm magazine into chambcr of the weapon.

(3) Squeeze trigger, allowing hammer to fall (fig. 54). Continue rest until third cartridge has been ejected from the pistol, simulating dry firing.

(4) When last cartitdge is ejcctcd, slide group should remain locked in open position by slide stop (fig. 55).

(5) Pistols that fail to meet rhc required functioning test will be corrected by replacement of defective components.
