    A Problem I Wish All My Guns Had

    I have been carrying a full-size M&P regularly for a year or so. Since early on, the locked slide releases by itself whenever a loaded mag is inserted. My compact version of the same gun never does it. Anyone know what causes it, or what can be done to make them all do it?

    I see more and more posts like this; none of my guns have ever done this. What am I doing wrong? Sounds like a nice feature, but everything I have read says it never happens 100% of the time. All the responses to people who report this say to never count on it working this way.

    my friend had a 9mm baby eagle that did the same thing. it took seating the some mag with a firm stroke, a gentle click wouldn't do it. Everything I had heard is that it is not intentional, and it is a result of the slide catch. if the notch in the slide is worn or deformed in such a way as the "slope" of the catch is the "wrong" direction, it *can* make it do this. same with the slope of the interfacing area in the slide catch itself. I would imagine with some jewelers files, some emery cloth, and some elbow grease with your thinking cap on you could reproduce the results. especially since you have almost identical guns side by side you just "make this one look like that one". Though like you say, it's ont gauraunteed to do it everytime.

    though my buddies baby eagle did it everytime you firmly seated a mag.... I thought it was great.

    Not uncommon in various makes and models, especially if you are very "positive" with your mag slap. I find it happens in all of my Sigs. Push the mag in as in an administrative load, and it stays locked, but during an emergency reload it often releases. The slide catch is a simple lever that holds the slide back with only a small bit of contact and no sort of lock or safety like a trigger sear would have.

    I've had one instructor in particular tell me to run the slide manually anyhow, with the philosophy that losing one bullet is better than having an empty chamber.

    Others have said to leave it be.

    I've done it both ways, but never, ever have found an empty chamber, whether I ejected the round or fired it.

    My glocks do it when I am enthusiastic in slapping home the magazine.

    My glock 32 does it. I know some guns are made so that if you slam the mag in a certain way it releases the slide. Also if you slam it in hard it will happen more frequently. I wouldnt get accustomed to it though unless it happens every time. You dont want to be in a gun fight and expect it to happen and it doesnt and you poke your head out with out a round chambered.

    I have to 'slam' the magazine in for a possible slide release. I just tried it, upon reading this, in my Shield and it [slide] released. Some of my M&P's do it, others don't. My Glocks, not so much.

    According to the gurus at my LGS, this is the nature of the poly framed beast. Use them enough and the slide releases when the mag's inserted, usually forcefully. If it's any consolation, I'm told Glocks do the same thing. FWIW, I've got a FS, Compact 9, and a Shield. None have done this,,,yet.

    I first heard of this with the Beretta 92. With the 92 it is the angle that the gun is held and the force of the reload. I tried it with my p89 and it will do it at a certain angle as well. Try pointing the front of your compact farther up and slam a mag in. I am interested to see if it will do it....

    Ok, just 'accomplished' this with my G19 gen 3, my fullsize M&P 9mm and my M&P 9c 9mm as well.

    Have had it happen with a few pistols, always while slamming a mag with a pretty good slam. It throws me off (reaching for the slide when it's already forward) so I've backed off my mag seating a hair and don't have it happen much anymore. This was on -G23,G19, CZ P-01, and M&P compact.

    Not something you can count on, so it isn't something I would train myself to expect.

    The number of people killed because they didn't have "enough gun" is dwarfed by those who had none at all. Get a gun you will always carry, and add more capability as you grow.
