Manual

This USFA pistol is ready to fire when a loaded magazine

is inserted into the pistol, the slide pulled back to cock the

hammer, and then released to travel forward and feed a

round from the magazine into the chamber. Final forward

slide movement locks the barrel and slide together and

deactivates the disconnector.

When the pistol is grasped, the grip safety is released so

that the trigger may now be squeezed. When the trigger

is squeezed the trigger bar acts to disengage the sear

from the hammer. The hammer pivots forward under the

force of the mainspring to strike the rear of the firing pin.

The firing pin is driven forward to strike the primer in

base of cartridge.

The energy imparted to the primer ignites it; the primer

in turn ignites the main powder charge which in burning,

rapidly generates extremely high gas pressure to drive

the bullet down the barrel. Rifling grooves in the barrel

impart stabilizing spin to the bullet so that it will follow a

more accurate path to the target when it leaves the

muzzle.

Force rearward on the slide breech face starts the slide

and barrel on their rearward travel; however, the slide

unlocks from the barrel only after gas pressure is reduced

to a safe level. Rearward slide travel depresses the

disconnector, carries spent cartridges rearward on the

extractor until the base of the cartridge is struck by the

ejector to propel it through the ejection port.
