Where is the firing pin on a pistol

This spring is conveniently mounted upon the pivot 12 of the hammer lever member 10 one end 13 of the spring engaging a projection 14 on one arm 22 i. A light coil spring 16 see particularly Fig.

The inner end of this spring engages the under side of the arm 6 extending from the trigger 5 and assists in maintaining the trigger sear 7 in its cocked engagement with the hammer lever notch 8. The outer end of the spring is engaged by an adjusting screw 19 in the trigger guard. Adjacent to this spring 16 is a screw 21 the inner end 24 of which serves as a stop by engagement with the under side of the arm 6.

The two screws 19 and 21 are secured against unwanted rotation by a friction tight locking pin 20 of soft metal or other suitable material. However, priority has to be given to the crime scene scenario where cartridge cases have been recovered but not the weapon.

The design of the trigger, hammer, safety and disconnector is such that it cannot be made to fire full-auto by removing or modifying the semi-auto parts. A firing pin is a lightweight part, which serves to transfer energy from a spring-loaded hammer to the primer, while a striker is usually heavier and is directly connected to the spring providing the energy to impact the primer.

The firing pin or striker is generally located in the bolt of a repeating firearm. A firing-pin safety is most often found as a spring-loaded part located in the slide of a pistol. Its job is to prevent the tip of the firing pin from protruding through the breechface of the pistol to contact the primer of the chambered cartridge until the trigger is pulled to fire the gun.

Firearms that do not have bolts, such as revolvers and many types of single-shot firearms, generally have a very short firing pin in the action frame, or else attached to the hammer itself. It mechanically interlocks with the firing pin to hold it in a safe position until it is disengaged by pulling the trigger. They just have to ride in a hole in a reasonable fashion and hit the primer within a fairly loose area. The final item to address in most firing pin jobs is the rebound spring, if one is required.

Most modern guns are designed so they cannot fire when dropped. In a striker fired gun, the hammer and mainspring have been eliminated from the frame. Instead, the mainspring has been moved up into the slide and acts on the firing pin directly. Except, now, the firing pin is called a striker. Rather than being hit by a hammer, it does the hitting itself.
