Break-in issues with 9mm M&P Shield Compact

[Beendare]

What you are describing happens to my niece when she shot both my M&P pro and the Shield. [thats not meant as a backhanded comment!] I haven't had the problems you describe with function...but yeah, those mags are tight.

Her grip and rip is a little more deliberate than mine, thus the hangups......and i suspect that is the problem especially with it being a new pistol. That Shield is hard to get a good tight grip on with larger hands....experiment and I bet that does it.

I really didn't like my Shield till it went through about 500 rounds. With that said, I still need to use a lula to put in the last round on both my mags. The springs are still really tight.
