For Positive Ignition & Reduced Risk Of Misfire
Replacement firing pin has a larger surface area on the impact point than the factory pin to help ensure positive ignition. Reduces chance of a misfire with ammo made of slightly harder than normal brass. High surface hardness resists wear, too, so you can fire thousands of rounds from your Ruger® .22 pistol.
