Mark 23 Primer Firing Pin Drag Old4eyes said: this causes, on occasion, for the laser cartridge to remain on after the trigger is pulled. some pistols have small springs in front of the striker to achieve that retraction. xd, xd m calls it "striker dampening spring" item #30 below. most of the guns though rely on gas pressure and mechanical recoil action to retract that pin. The only time it could possibly help you is offhand shooting. it has been proven with benchguns, both short range and 1000 yards that the lightweight pin hurt accuracy. when dwight scott tuned bat actions he added tungsten carbide to the pin to make the pins heavier for consistant ignition and better accuracy. matt. Cratering can be from an overly large firing pin hole, the off center primer strike can be caused by the bolt bring a loose fit in the receiver, the firing pin hole off center in the bolt, and even a bent firing pin (which could drag and cause light firing pin strikes). fist off disassemble the bolt, clean it completely, roll the firing pin on. The firing pin spring is one possible cause, but the firing pin channel may be full of crud. the crud, if it is there, may be preventing the return of the firing pin. a squirt or two of non chloronated brake cleaner may allow the firing pin to move freely. the firing pin lock should move freely and its return spring should operate normally. bill.

But i do have a kahr cm9 which is smaller yet doesn't have primer drag. here's how i imagine it happens: after firing the barrel starts unlocking dropping down while the firing pin or striker is still extended outward. the case stays in place because the extractor claw and the chamber walls hold the brass oriented facing forward and tight to. Since the recoil spring is stronger now the slide chambers a round now with more force. the new stronger firing pin spring keeps the firing pin from flying forward and hitting the primer on the round going in the chamber. this is the purpose of the stronger firing pin spring onj a 1911 without the firing pin lock.
