Comparative Anatomy of Pistols
All pistols are more or less similar to each other.
The gun consists of the following components:
- Trigger (trigger mechanism),
- return mechanism
- shutter lock
- gun shop.
The frame is connected to the pistol grip and trigger guard. This is a fastening part that combines and makes the parts and mechanism as a whole.
A magazine fastener with a spring is attached to the frame (this keeps the magazine from falling out).
The barrel is fixedly mounted with the frame rack (it is fixed with the help of a transverse pin). On the muzzle of the barrel is the base of the fly, and the fly itself, which is attached with a screw. Using the fastening screw of the front sight, you can change its height.
The sight consists of a base (riveted to the frame) and a rear sight (secured by a fixing screw). The whole, like the front sight, is movable, with the help of a fixing screw it can be moved to the right / left. After moving to the desired position, the rear sight and front sight are fixed with the same screw (so as not to “move out” when shooting).
The shutter is responsible for bringing the trigger to the firing position (platoon) and locks the barrel, as well as for releasing / retrieving the cartridge from the magazine into the chamber and from the chamber.
In the shutter, the following parts are distinguished:
- skeleton with a rammer;
- a drummer with a spring (during a shot hits the cartridge capsule);
- ejector with a spring (removes the cartridge case from the chamber).
The drummer is the rod on which the breakaway spring is attached, which leads the drummer into the bolt.
Trigger (trigger mechanism) consists of:
- trigger (with traction and axis),
- war springs
- trigger thrust
This mechanism works in the following order. The sear is designed to lock the trigger in a combat and safety position. The trigger with the trigger pull shifts the sear when pressed (unlocks the trigger). The trigger drives the drummer. Trigger uncoupler eliminates accidental operation when the mechanism is not fully brought into combat position. The mainspring is connected to the trigger. The limit screw adjusts the trigger stroke.
The trigger spring returns the hook to its original position after being pressed.
Trigger spring biases the trigger rod to the top.
The shield secures the hook and its springs, as well as the trigger pull from falling out. Attached to the frame with a fixing screw.
The fuse limits the bottom of the sear and thereby prevents the spontaneous movement of the trigger.
The return mechanism returns the shutter to its original position.
The shutter lock limits the backward movement of the shutter.
The gun store is a part for placing ammunition.
Some pistols have lining made of wood, rubber or composite materials on the handle, they are designed to more conveniently hold the weapon and prevent it from slipping out when firing. Pads are called cheeks.
