G43 Hammer Spring

The G43/K43 Hammer Spring is responsible for generating the force required to drive the hammer forward and strike the firing pin assembly. Correct spring tension is essential for reliable primer ignition and consistent operation of the rifle's trigger mechanism.

After decades of service, the original hammer spring can weaken through repeated compression and metal fatigue. A reduced spring force may contribute to inconsistent ignition or light primer strikes. Replacing the hammer spring restores the correct operating force and helps maintain dependable function of the firing mechanism.

Manufactured from premium-grade spring steel and heat treated for maximum durability, this G43/K43 Hammer Spring is produced to precise dimensions for an accurate fit and long service life. It is an excellent choice for rebuilding the trigger group, replacing worn internal components, or carrying out a complete mechanical restoration of your G43 or K43 rifle.
