    Strange Glitch in my Sig...

    Ok...

    So the last round of the magazine sometimes fails to feed properly because the slide remains stuck OPEN. As if the gun thinks its empty and wants a new magazine. I cant bump the slide to chamber the round because it is stuck open as if the gun is empty.

    It happens about 2/10 times.

    The gun is a SIG P229 in .40

    ANYBODY else ever experience or heard of something like this?

    Is it the same magazine?

    It sounds like you need a new magazine spring, or at least clean the inside of the mag

    I can say with confidence this is a magazine issue. The magazine follower is probably prematurely engaging the slide stop.

    Try a different mag, or as pgrass101 suggested, put a new spring in the mag and clean it (but never use any more than a super-thin coating of oil inside a mag, oil can render primers useless).

    Just wondering, does it do it with both FMJ and HP ammo?

    Peace,
    Pete Zaria.

    Check in on the Sig forum,on the Armorer's board. Not uncommon, and basically 1 of 3 things:

    • Mag. (hint, hint)
    • Slide release spring bent/too strong/not in place
    • Shooter's thumb.

    Sig mags only and clean them should fix your problem.

    Return the mag for a new one.
    That's right, this sweet baby was made in Grand Rapids, Michigan. Retails for about a hundred and nine, ninety five. It's got a walnut stock, cobalt blue steel, and a hair trigger. That's right. Shop smart. Shop S-Mart. You got that?

    How many mags do you have for that pistol? If you have 2 or more, then I would put a small piece of masking tape on the bottom of each one and mark them 1,2,3, etc. and try each of them again. When the problem arises make note of which magazine is in the pistol. Try all of the magazines and if it is only one or two, then send those back to Sig Sauer for replacement. If it is all of them, then it could be your slide release or thumb as others have stated.

    Thanks for the suggestions. The magazines are as new as the gun (<2mo. old)

    Will clean and mark both.
