Mini 14 firing pins have gotten a bad rap lately. They have been known to fracture the tip but can be repaired successfully with the correct process.


There is available, in limited quantities and only through the


Ruger Factory or two selected gunsmiths,  a new design firing pin.


In my opinion, there is no better firing pin than one produced by the Ruger Factory. Fitting is required and necessary for safety and function.


There are aftermarket firing pins but seem to be of questionable material and hardness. They are all two piece with slightly different designs. Each design has ti’s faults. They are still good to have as a spare backup in case of emergency until a factory FP can be obtained or the original stainless factory FP is re-tipped. This is a a specific process using hardenable 17-4 TIG rod and heat treating H900 and back to factory specs.
