M&P 9mm mag hanging up
 

I know ive put this on before but i'll try it again. My buddy has a 9mm abd the follower is hanging in the cut out on the mag. I put this on before and was told to make sure they were clean, we cleaned them very well and oiled them up but the problem persisted. This is the second set of mags hes had, the gun shop gave him 2 more when the others started with this problem. Now the new ones are doing it, they have about 400 rounds through them when it starts to hang up.
Any help would be greatly appreciated, thanks.

I would send it in to Smith and Wesson.

Can you post some picks? You may be able to alter the follower slightly to fix the problem.

I will try to get some pics soon to post .

Here are some pics of what is happening.

those aren't the stock mags are they

Yep thats wgat was in the box. I cant figure out why the follower is short and narrow when its pushed down it half the width of the mag. But im used to single stack mags. I really like this 9 and like the feel of it, im considering getting one myself.

you got a better shot of the magazine full veiw because the picture you have is a little fuzzy

Here is a coupl more pics
The second pic is with the follower caught in the mag catch hole
The only thing we have done is change the mag release to the other side for the left handed wich he is

I'm left handed, and never had any issues with the mags.

Maybe the spring was put in wrong?
