    and therefore activate the slide stop before the magazine is empt?

    Where does the magazine follower make contact with the slide stop?

    I have a slide stop that is occassionaly locking back before the mag is empty, and want to file it down some to keep the bullet from contacting and activating it. Which facet needs to be filed?

    Put down the file!

    I'd get a replacement slide lock and try that. It's cheap and saves your original part.

    It's probably something out of spec with the slide lock. The easiest way to see what it is involves a "known good" part for comparison.

    Only when I was absolutely sure what to remove would I start filing. :)

    The part of the magazine follower that hits the slide stop depends on the follower design. On the traditional follower, it is the bottom flat of the "L" at the front of the follower. This usually hugs the magazine contour fairly closely.

    The round nose of the bullet misses the slide stop, but the "L" is designed to catch it.

    More modern followers are sometimes V-shaped, made of polymer, etc. but they all have to have some kind of "step" to engage the slide stop.

    What is your grip style? Some people have there weak hand thumb laying beside the frame and hit the slide stop on recoil.

    uneasy_rider, after going over your grip style to see if what Majic says is a possibility (It is a very real possibility)...then look at the slide stop. If the slide stop is impacting the bullet, you will be able to see copper/brass on the EDGES of the stop. Once you see this, then strip the slide off and put a loaded mag in there and see where it can hit. These will be the same spots that have copper on them. Then take an unloaded mag and notice where the follower contacts the stop. Make sure to leave enough room for it to engage the stop if you want it to continue to lock back on the last round. It isn't hard, but like everything, go slow, you can always take more off, but it's really hard to put it back on.

    I had to do this on my 2 1911s, but neither of them induced a malfunction because of that.

    Cheesy mags and extended slide stops cause a lot of that sort of trouble with 1911 auto's.

    I just went through this with a Springfield Milspec. Cheesy mags were my problem.

    If you file the slide stop, beware that too much, and the follower can pop over the slide stop and then the mag is stuck in the pistol.

    Bullet profile can cause this issue too. The bullet touching the slide stop and activating it.

    If you have an extended slide stop, try putting your thumb somewhere else, or swap a standard slide stop into the gun. Try a different mag. Try different bullets.

    I've also noted that pistols with loose magwells tend to have these issues more so than pistols with tight magwells. I guess everybody wants their mags to drop free, so manufacturers have enlarged the specs a bit. Stick a standard size mag in, and maye the slide stop nub doesn't protrude far enough anymore. So the makers put in slightly enlarged slide stops. Then the trouble starts!
