CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwanese Patent Application No. 108137482, filed on Oct. 17, 2019.

FIELD

The disclosure relates to a pistol frame.

BACKGROUND

Due to the fact that a pistol has few components and a simple structure, and is durable and reliable, it is often used as a gun for a police or a toy gun for a survival game. Its appearance and interior structure are constantly updated to satisfy the use requirements of different units, the experience of using the gun and the desire of collection of consumers. After using the pistol for a certain number of years, only the frame must be replaced, and the inner components, such as the locking block, the trigger, etc., made by the original manufacturer may still be usable. Thus, some manufacturers will only make plastic frames for the pistols, and the user can remove the inner components from the pistol made by the original manufacturer and install them into the new plastic frame to produce a new pistol with plastic frame.

The trigger must rely on a trigger mechanism housing for it to be disposed on the plastic frame of the pistol. Since the triggers of different generations of Glock pistols have different structures, the existing trigger mechanism housing cannot be commonly used. Moreover, after a bullet is fired from the pistol, the slide of the pistol will move rearward and eject the spent shell. Since a strong reaction force is generated at the muzzle of the pistol the moment a bullet is fired, a front end of the slide is lifted up slightly, and a torque is generated on the locking block, so that the existing locking block may be damaged due to the lifting of the slide.

SUMMARY

Therefore, an object of the present disclosure is to provide a pistol frame that is capable of alleviating at least one of the drawbacks of the prior art.

Accordingly, a pistol frame of this disclosure is suitable for mounting of a trigger mechanism, a slide and a barrel thereto. The trigger mechanism includes a trigger mechanism housing having two legs, two extensions extending downwardly and respectively from bottom front ends of the legs, and a through channel extending through the trigger mechanism housing in a left-right direction. The pistol frame includes an upper frame portion, a handgrip portion and a rear rail block. The upper frame portion extends along a front-rear direction transverse to the left-right direction, and is suitable for mounting of the slide and the barrel thereto. The upper frame portion includes a rear section that defines a rear receiving space. The handgrip portion is connected to and extends downwardly from the upper frame portion. The rear rail block is disposed in the rear receiving space, and is suitable for receiving and supporting the trigger mechanism housing. The rear rail block includes a bottom plate, two side plates extending upwardly and respectively from left and right ends of the bottom plate and configured to be located at two lateral sides of the trigger mechanism housing, and two rear rail portions extending transversely, outwardly, oppositely and respectively from top ends of the side plates for forward and rearward sliding movement of the slide thereon. Each side plate has a through hole. The through holes in the side plates are configured to align with the through channel for extension of a trigger housing pin therethrough, thereby fixing the rear rail block and the trigger mechanism housing to the upper frame portion. The bottom plate and the side plates cooperatively define at least one receiving space suitable for receiving the extensions.
