    On and STI 2011 other than magazine/follower what can cause slide from not locking back on last round/empty mag while shooting. Thx

    Modified slide catch, underpowered ammo, anything that can cause the issue in a single stack.

    Yeah a lot of people that shoot uspsa will cut the follower or the catch on the stop pin so it won’t lock back on an empty mag. I’m not sure why, I just know it’s common

    I've been told the reason for not wanting an STI 2011 to lock back after the last round is fired, is because in the stress of competition sometimes on reload the shooter will jam it in so hard he gets the extractor out of whack. Just what I've read.

    Way back when I shot USPSA, many folks would disable the slide lock (one way or another) to prevent inadvertent slide lock during a stage run.

    I just deepened the 'dimple' on the back of the slide stop to prevent unwanted engagement, yet still function on a empty mag.

    I don't know about the more casual shooters, but those I shot with (including myself) always knew how many shots I had taken and what was left in the mag, because nothing blows a stage quicker than 'running dry'.

    NO chance of the slide accidently locking back..Reload where you WANT to, not where you HAVE to. This does not always apply to single-stack/production 8-10rd guns. especially when there are 8 pieces of steel in an array.. then: I prefer them to function as designed.
    "Course design and construction must not require more than 8 scoring hits from any single location or view, nor allow a competitor to shoot all targets in the course of fire from any single location or view."

    I've been going through some slide lock education over the past couple of weeks. Sometimes the lug on the slide lock is out of tolerance and the follower doesn't have enough purchase on it and slips to the side of the lug. You can hear it 'click' as you insert the slide all the way.
    In my adventure to figure out why it happens, I've found it's more times than not caused by two factors:
    1. Follower gets chewed up. Gen 1 MBX Extreme followers are an example of this. I replaced all of my Gen 1 followers to the beefed up Gen 2. Take the slide off your gun, put the slide lock back into the frame and insert a mag slowly. What happens as the follower touches the slide lock?
    2. Spring in the mag is weak. Amazing how quickly the springs get compressed. I test it by removing the spring, manually stretching it out a bit, putting spring/follower back into the mag, and if the follower locks back the slide, time to replace the spring.
    To a lesser extent there's the Gen 1 STI mags. They're just a piece of shitt in the first place and should be avoided. I think they fail sometimes because STI designed them to do that so you had to pay a smith a ton of money to 'tune' your mags. Got about 4 or 5 I'm going to swap out eventually to all MBX Gen 2s.
    For reference, I did a two day Steve Fisher (Yeti) course this weekend with my wife. We both used a 2011 of some type, and I used STI Gen 1, Gen 2 and MBX mags. Only the MBX mags didn't have critical failures of some type. The STI's had follower issues where they would slip to the side and the rounds would rattle around in the tube. Pathetic.

    Murphy's Law is at peak performance during any kind of competition, timed drill, training scenario or in real life SHTF moments. That's why we train for failures to happen. And they like to happen at the worst possible moments. Fortunately, in gun games, it is not a life/death situation.

    Make sure you’re not riding the slide stop.

    Generally hard to do on a 2011. The frames bury the slide stops and have raised areas where the grip meets the frame, instead of having them stick out like on a 1911.

    Yeup, but people get overly aggressive with grip.

    Make sure you’re not riding the slide stop.

    The reason why I really enjoy shooting the 2011 is precisely because with my huge hands and long fingers I tend to hit the slide stop and with the 2011, because it has the 1911 style safety it really keeps shooting hand thumb away from the slide stop and as per the previous comment, the slide stop is closer in.

    True, true. Watched a medical officer once jam a Beretta slide in backwards running a range, so...

    Wow, well....anything worth doing is worth doing right. If you are going to really screw up, he excelled.

    I watched a buy load up a magazine with all the rounds backwards. I should have stopped him but I could not tear my eyes away and say anything.

    The main reason it gets disabled is due to the design of the 2011's frame; it'll allow the 140mm and 170mm mags to over-insert and can cause the ejector to bend.

    Unless the shooter uses a specifically designed mag catch to prevent the over-insertion.

    Your second quote basically contradict the first one...LOL.

    What you "Want to do" vs "what you actually do," once the timer goes off are two different things.
