Stage 1: As the Trigger is pulled, its "front-hump"radius bears on bottom of receiver, causing the Sear to begin to descend.
The "rear-hump" of the Trigger makes contact with bottom tang of the receiver. (This contact can distinctly be felt).


Stage 2: Continuing to pull the Trigger causes it to lever on the "rear-hump" and draw the Sear totally out of engagement with the Cocking-Piece. The Striker is released.
