| Theory of Operation of the Colt .45 ACP Government Model Pistol (1888 words) |
 | When the slide is in battery with a live round in the chamber, the hammer cocked, the safety lock off, the grip safety depressed and the trigger pulled, the rear lateral bar of the trigger bow presses against the front side of the disconnector's paddles. |
 | When the sear is in the full cock notches of the hammer (with the safety lock off and the grip safety depressed), pulling the trigger causes the sear's nose to move out of the full cock notches and permit the hammer to fall against the firing pin. |
 | When the grip safety is being normally depressed by the web of the shooting hand, the lower section of the grip safety pivots forward (the top section pivots rearward) and the tip of the bar on the right forward side of the grip safety moves above the lateral bar on the trigger bow. |
