    There could be a couple problems. Has the recoil spring in the stock been replaced as it can become weak and not close the bolt all the way after the first shot is fired. Another place to look would be the firing pin spring can break. After it happens is it only after a shot is fired or does it happen on the first shot as well?

    I had a similar experience with a 391. I believe I tried everything, switched out parts with another 391 and eventually sent the gun to Beretta. They worked on the gun and it still hiccuped. I'm embarrassed to say the problem was a primer I switched to. (don't you think you would figure that out before you went through 4500 primers). Anyway don't overlook the primer.Kenny Bruggeman

    The firing pin spring is more than likely the culprit. Once it breaks, it winds around itself and binds on the pin when struck,,,,,,sometimes!! I just had to replace mine recently too.

    I'd bet on firing pin spring, like Hap said.

    This spring holds the firing pin "BACK" so the hammer gets a good firm hit on it.

    If the firing pin isn't held back far enough, you can get light hits.

    Firing pin spring, at a glance its not noticable as it winds upon itself and still looks like one piece.

    It also may be as simple as cleaning the chamber well- if the shell is just a little tight in a dirty chamber and then moves forward (through the crud) at impact that could be it

    They also had a problem with different shells at different times- Remington gun clubs had some primers that were visably seated too deep-

    You can also have that happen with a home reloader

    I had this problem with my Extrema II. I cleaned it but it did not immediately go away. I just kept shooting it and it seems to have gone away and stayed away for over a year now. Knock on wood. I wish I knew what caused it but I'm just glad it hasn't cost me anything to fix.

    I have had this problem and it has always been the fireing pin spring break in mine and others that I have seen it happen to. I guess if your gun gets really dirty in the bolt I could see it happen then to.Just my experience.

    are you using remington gun club shells??? They had an issue with a batch of them a few years back. The primer was changed from brass to steel and the steel was like a spring and the firing pin wold just put a small dent inthe face of theprimer and then the second time it would go off. If you contact remington them might replace the shells. It depends ont he date code on the bod. I believe the bad ones started with a d or an e. check them. motordoc
