Abstract: The present invention relates to an "IMPROVED SAFETY DEVICE FOR SEMIAUTOMATIC PISTOL". The safety device comprises a three-position safety register in which a raised position (A) actuates a pistol locking mechanism and a lowered positioned (B) actuates an uncocking mechanism of a hammer with automatic return to a horizontal neutral position (C) allowing shooting with the pistol.

Abstract: The patent of invention "IMPROVED SAFETY DEVICE FOR SEMIAUTOMATIC PISTOL" discloses a safety device that comprises a set of pieces specially configurated to operate either to lock the pistol and to decock the hammer safely as well.

Abstract: The invention pertains to a method of manufacturing a semiautomatic pistol, wherein the pistol frame is made by cutting, stamping, folding and welding a metal sheet, and then the working parts of the pistol are assembled with the frame.

Abstract: An aiming system adapted for use in competition revolvers incorporated in the upper portion of the revolver and includes a heavy steel rib along which the various components of the system, namely, the rear sight, the front sight, and an auxiliary weight, can be displaced and fixed in desired positions. The rear sight is micrometrically adjustable in height, direction and opening of the rear sight slot and the front sight is constructed and arranged for receiving interchangeable inserts.

Abstract: A pressable magazine latch for semiautomatic pistols adaptable for use by either right or left-handed persons includes a guide-tube anchored wihtin the pistol frame which contains a displaceable rigidly connected two-part latch member therewithin. A spring normally maintains the latch member engaged with the magazine and presents a latch member button projecting beyond one end face of the guide-tube. Despressing this button substantially flush with the adjacent guide-tube end wall releases the latch from the magazine while further axial displacement of the latch member allows subsequent disassembly of the two latch parts to permit re-assembly thereof in a reverse position within the guide-tube.

Abstract: A retaining means for revolver cylinders includes a resilient bushing which, upon being inserted in the cylinder bore, is engaged in an annular recess in a hollow cylinder axle making it impossible to disengage the two parts from one another after introducing an extractor mechanism in the bushing and threadedly connecting a sleeve of the mechanism with the threaded end of the extractor rod.

Abstract: An actuator system for the trigger return in double-action revolvers includes an actuating rod having a rounded end engaged in a recess in the trigger with a helical coiled return spring biasing the rod by means of a cylindrical shoulder thereon and a rotary abutment member having a bore, which bore serves as a guide for the axially shiftable rod. The system provides an improved double-action operation since it compensates for the increasing reaction of the spring by reducing the lever arm or moment of this reaction on the trigger during its rearward movement. An improvement enables the user to control the "trigger weight" in a single-action operation by the provision of a return spring control bushing which can be adjustably threaded in the rotary abutment member to vary the effective operating length of the spring.
