Automatic pistol with select fire mechanism

An automatic pistol comprising:

• a frame with a magazine receiving grip;
• a slide including a breech-block at the rear;
• a floating barrel and the slide, movable on the frame with the breech-block engagable over the barrel to form a cartridge chamber;
• a spring loaded firing pin, with a foot at the rear projecting down, movable in the breech-block, away from and towards the barrel, between its rearmost position when it is out of the cartridge chamber and at the maximum extent of its travel to the rear of the breech-block, and its foremost position when it projects into the cartridge chamber, and including a rest position when it is fully contained within the breech-block between its rearmost and foremost positions;
• a trigger provided with a safety lever and with a trigger bar pivotally connected, said trigger bar embodying, at its rearmost end, a plate with a face on its rearmost top corner and a triangular hole with an inclined edge within, and a web extending sideways from the plate, said web embodying a wing extending further sideways from the web and with a ledge extending rearward from the web, the trigger and the trigger bar being moveable between their foremost and rearmost positions, in the same directions as the firing pin;
• an activating rod, embodying a foot and a groove, is transversely mounted in the frame and passes through the triangular hole in the plate of the trigger bar to co-act with the inclined edge within said hole to disengage the ledge from the foot of the firing pin when the trigger is in its rearmost position, said activating rod being transversely movable within the frame, on the slide's rearward movement, positioning the groove over the inclined edge for said edge to enter the groove and position the ledge into the path of the foot of the firing pin, a triggering mechanism including the trigger and the trigger bar, said trigger bar and the ledge having abutment means, are guided along their path by the inclined edge and the activating rod, said path being a gradually downward one towards the rear of the pistol characterised by the firing pin starting in its rest position with the ledge being positioned in front of the firing pin foot prior to the actuation of the trigger and the ledge being arranged to engage said foot to carry the firing pin in a rearward direction during the movement of the ledge along its path during activation of the trigger and to disengage from the foot, to release the firing pin to fire a cartridge, at the end of its movement when the trigger is in its rearmost position.
• a select fire switch with an inclined edge is positioned at the rear of the breech-block in line with the plate of the trigger bar and is switchable to position its inclined edge in the path of the face of the plate for said ledge to strike the face and force the ledge of the trigger bar down to disengage the ledge of the trigger bar from the foot of the firing pin when the breech-block reaches its foremost position;
• an ejector plate, for ejecting a cartridge, embodying a rectangular hole in its top edge to stabilise the ledge of the trigger bar as it is moved between its foremost and rearmost position;
• a magazine drop safety plate embodying a hook to stop the trigger's rearward movement by engaging over the trigger bar when a magazine is fully or partially out of the frame;
• an extractor, for extracting a cartridge from the chamber, embodying a ledge, a follower and a spring, said extractor being automatically retained in the breech-block.
