This is the exploded view drawing, with all parts identified and numbered. It also shows the general shape of most parts and their relationship to each other. The parts in this view are not drawn to scale.


This shows the action closed, locked and with the hammer in the "at rest" rebound position. This is the position the hammer is automatically placed after firing by the design and shape of the mainspring and mainspring strut. It is also the SAFE position in that the sear tip of the trigger is behind the SAFE notch on the hammer, blocking the hammer so that it cannot contact the spring retracted firing pin. Note the hole in the trigger in line with the rear adjustment screw in the hammer. Adjustment of this screw can only be made with the hammer in the rebound position. The rotary lock spring is not shown in the sectional view drawings but is shown in the accompanying detail drawing of the rotary lock and rotary lock release lever, and also in Fig. 4-16. The extractor plunger and spring (10) are also not shown. (See Figs. 4-1 and 4-7).
