    Firing Pin Positioning Pin Coming Loose

    All,

    I would appreciate a bit of advice on something that I've noticed with my SIG P239. Hopefully I can get some help with this one...

    I've noticed that while firing the Firing Pin Positioning Pin (Item 7 in the SIG exploded diagram) has a tendency to work its way out to the left side while firing. I'd say it starts to move out after about 25-30 continuous rounds.

    My question is what I can do about it and how serious of a concern it is. It does not move without force being applied, so it's not falling out by itself, but it's working its way out while firing. I'm sure it wouldn't be a good thing to have it work itself all the way out while firing... I'm just not sure what I can and should do about it.

    Anyone with any experience in these matters care to lend their thoughts?

    mine is a 1st gen p-239/40 with upwards of 3k rounds. not had a problem other then the left grip screw works loose every 100 or so rounds. though have never taken mine down to that level, i am thinking that it may help if you reverse it before inserting.

    BIG DISCLAIMER I am not a gunsmith

    This looks to be a simple roll pin. I'd remove it and open it up a bit by carefully inserting a small punch or something.
    The increased diameter should help it hold better.

    however, I am not a gunsmith I was brought up juryrigging stuff and making things work. I'd ask an experienced gunsmith before taking my advice.

    If the pin is backing out it should be replaced with a new one. Is this a new or used gun? If it's used it's possible someone tried reusing the pin after a teardown which isn't recommended by SIG.

    Okay, I'll give SIG and see if they can send me one and give me an opinion on it as well. The gun has only had one owner previous to me, another forum member here, and I'm not thinking he would have done something like that but I'll check with him.
