    Yes, a snap cap is jammed in the chamber of my Sig P320. I've tried everything I can think of, and just watched a YouTube video in which another P320 owner had a similar problem, and said he was sending the gun back to Sig.
    Do any of you have any tips or tricks for unjamming the gun? I can't pull down the slide release far enough to take it down that way, due to this same jam.

    I would try taking it to a local gunsmith before sending it all the way back to Sig.

    Blow a metric crapton of WD-40 down the barrel - leave it sit for a day, barrel side up.

    Try again. Hopefully you avoid breaking the extractor.

    Beat the slide against something to force the slide back open.
    I've cleared stuck rounds from my 1911 and Beretta92 doing this. I was chambering reloads to make sure they were not too long. Well they were too long by about .01 inch.

    I've done this many times at the range, and it works, but it's painful to my old hands. So I started teaching the jammed guns owners how it was done. Sure enough, it works for them too.

    From a one handed firing grip, with the pistol held close across your chest, reach over the top of the slide and grab it firmly with the non-shooting hand. Release your shooting hand, while still firmly holding the slide. Draw your shooting hand back about 6" and then SLAM your hand back into the grip. Hit it like you want to drive the grip right out from under the slide.

    If it works, you'll be picking up the ejected snap cap, and will have done zero damage to the pistol. I've had 100% success with the technique.

    If you have to do this with a jammed live round, just be sure to keep the muzzle in a safe direction.

    I would place a dowel rod into the barrel and then press it into the snap cap by pushing against a solid object, at the same time I would be attempting to retract the slide. This gives you pressure on the snap cap from both the front and rear.

    I was hoping we'd hear something by now.

    It could be a useful training tool. Load up some dummy rounds just long enough to stick in the barrel and practice rapid, field expedient clearing methods to get the gun back in service. Otherwise, it's just a poor hammer.
