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.
Please see the pics at the bottom of this page.
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.

Below is the current updated FP Ruger now uses. Note the wrap around shaft with a groove cut into it giving rigidity.
Proven durable over the years unless corosive primers are used or fitting was done incorrectly and not leaving clearence at the tail of the FP causing stress on the tip having the hammer pushing on the tail while the tip is still in the primer pocket. IMHO.
