Re: New 500 won't fire
It is very difficult to get the pin to protrude from the bolt face. The firing pin spring is super stiff. I am taking it apart now to make sure there isn't any defect on the firing pin.
ETA: OK, took it all apart. The pin slides back and forth fine, and there is no sign of binding. I did find a bit of a burr on the firing pin near the striker end, where the factory drove the firing pin retaining pin in. I smoothed that off, along with some burring on the inside of the piece on the bolt that the pin sits in.
