I Bought A Wilson Firing Pin ( Just To Have Extra One ) For My Springfield Trp And It Dont Fit The Pin Is To Big . Is This A Peace That You Have To Fit To The Pistol ,or Do I Need To Take It Back.
Springfield has used a number of sizes over the years, but I believe the latest pins are between a standard .45 pin and a 9mm pin.
Either get the correct pin, try a 9mm pin, or ream the slode to take a standard pin diameter for the caliber.
