In firearms terminology, a floating firing pin is one which is unrestricted by a firing-pin return spring or similar. While it will be captive and unable to simply fall out, either forward or backward, it is otherwise free to slide within these stops. The trapdoor Springfield Model 1865 is an example of a floating firing pin. [11]
The free-floating firing pin of AR-15 style rifles typically causes an indentation as the firing pin lightly strikes the primer when the bolt closes as it chambers a loaded cartridge. Although a single light indentation may not detonate the primer, [ 2 ] the indentation may make the primer more sensitive to subsequent impact.
From the top: striker-fired, linear hammer with free-floating firing pin, hammer-fired with free-floating firing pin, and hammer-fired with integral firing pin. The hammer is a part of a firearm that is used to strike the percussion cap/primer, or a separate firing pin, [1] to ignite the propellant and fire the projectile.
The firing pin in the SVD is not retained, i.e. "free-floating", and it is therefore possible for accidental discharge to occur as the bolt pushes an unfired cartridge into the chamber, should there be an obstruction in the firing pin channel resulting from poor maintenance or extreme cold.
[47] [48] The original design features a free-floating firing pin. To theoretically reduce the risk of slam-firing, the HK416 and its civilian variant MR556 feature a proprietary firing pin safety in the bolt. Such firing pin safeties may obstruct the upper from working with standard AR-15-type full height hammers located in the fire control ...
Mainsprings should not be confused with the type of firing pin spring which is utilised in some designs instead of free-floating firing pins to prevent slamfire. Parts sketch of the firing mechanism on Russian infantry rifle model 1845.

Unlike the Sten, and its Polish clone called the Polski Sten, it employed a free-floating firing pin and two springs behind the bolt – one served as the return spring and the other as the buffer spring (similar to the later Sterling submachine gun). The weapon was designed in this fashion so that resistance army members could use any captured ...
