M&P45 Magazine Issue

[averagejoe46048]

I recently picked up an M&P45 and one of the mags will only take 9 rounds instead of 10. Has anyone else run into this issue and if so, know of any solution short of S&W Customer Service?

Shoot it some and the mag will loosen up enough for th 10th round. They are very tight new.

The M&P 45 mags are very VERY tough to pack full. Load and shoot with as many as you can in there and it will eventually loosen up. It took several uses with my M&P45 for it to finally get where you could get 10 in there.
