With the trigger in the rear position, the striker safety plunger is depressed, allowing the striker to move forward. You should check periodically to ensure that the pin is free-floating like that. If it doesn't rattle around with the plunger depressed, you've probably got gunk in the striker channel.Polished pin surfaces. 3.5# spring. TI safety plunger. Why does my firing pin move with the trigger in the fully rear position?
His gun is the faulty one; that pin should rattle around something awful any time the trigger is in the rear position. Get it cleaned up ASAP!Thanks. I was wondering bc my dad just bought a gen 3 17 and his pin doesnt move at all in the safe position . Sorry about the language. It was bugging me.
