m&p 40c issue

[Sam1]

I can't get a full magazine to go in the gun when the slide is forward, if I take a round off then it seats. Is this normal for all m&ps? I've tried two magazines and same thing. Does it have something to do with the mag safety? I've only owned sigs and never had this kind of problem, so I'm just curious

mags just need to be broken in a little bit. Glocks do it too.

You don't need to be gentle, it'll fit.

Give it a whack with the palm of your hand to seat it, then leave it like that over night or for a few days to break in the spring.

That's what she said...

I'm gonna try your suggestions then take the mags out tomorrow at angeles for some range time and see what happens

Any chance that you’re having to force that last round into the mag, really force it? And If yes is the round tilted slightly upwards compared to the rounds beneath it?

[Sam1]

I can get the last round in on both my mags but it's a tight fit and the round is in the same position as the previous round. I think this is why the mag wont easily go in when it's fully loaded on mine. Just a flaw with the mags I guess or they just need to be broken in.

I tried using a bit more force to get the magazine in and it went in, thanks guys! I also just came back from angeles and out of 200 rounds this thing had 0 failures. I'm going to leave the mags loaded for a while hopefully that takes care of it. Oh and I was way more accurate hitting steel targets with the m&p than with my sig the steel targets also moved a bit more violently

Just needs broken in

Like others said, jam the last round in and leave it full for a couple days. Having a mag loader like the upplula makes this super easy. That may be the best gun thing I've ever purchased.

It is just a tight magazine spring...S&W is just concerned that stacked tolerances would produce an 11rd mag

Check out the “resolution” to this thread. It might help.

I have a S&W M&P .45. Same thing.
