    After the last shot has been fired and the casing ejected, the slide does not lock back. It moves forward as of it chambered another round. What could be the cause of this?

    A weak mag spring, a dirty mag, a follower with the tab that actuates the slide stop broken off, weak ammo, or a very weak grip could cause this. The tab on the slide stop itself, that gets actuated by the mag follower, could be broken off as well.

    Does the slide lock back on an empty mag if you pull it back manually?

    Or, that your non shooting hand's thumb was riding the slide stop. This is fairly common with Sig pistols.

    Assuming that you're shooting right handed, I would guess it's this as well. Try putting the thumb of your right hand over your left hand like this http://www.kyledefoor.com/2009/06/sig-sauer-secrets.html and see if it still occurs.

    Yes the slide locks when I manually pull it back. The gun itself is around 7 years old if that adds any insight with all the original parts and mags. Ive never had problems with it until these past two weeks when I've gone to the range twice and noticed it happening. It happened about two to three times last week and the same this week. I'm leaning towards it being a mag issue too because I've had a problem with another one of the originals that I tossed about a year ago.

    +1000000000. Probably the most common cause. Pay close attention to where your thumb is when you shoot. Took me a while to adjust but once you do you shouldn't have that problem anymore.

    If it's seven years old it's most certainly time for some new springs.

    If it has happened to two different Sigs, I'm leaning towards you. Shoot it with your left hand only and see what happens.

    If its not you, it certainly sounds like a mag spring problem.

    Yeah like I said, I'm pretty sure it's just the mags or some springs. I highly doubt that after seven years I'm just now starting to make common mistakes for new sig shooters.

    Sounds like a mag spring problem.

    Unless you've somehow managed to screw up your hand position without noticing, I'm going with magazine spring. See if you can isolate it to one or two magazines, and replace the springs in the offenders. If it's every magazine, it's either the gun or it's you.
