First Handgun - S&W M&P 9mm

[enefgee]

I have 3 different generations of 9mm mags for my M&P - they all start out very tight and they all break in, if they're out of spec you can grind down the follower tails. On the plus side, I've beaten the springs in these suckers half to death and still haven't had feeding issues.

The older blued mags are great. The newer black mags suck big time. The follower bottoms out on the base. My fiz was to dremel down the legs of the follower making sure I kept the same angle on the follower. Both mags now work fine. I would like to see Megar make mags for the gun using a full steel set up with a pressed dimple to restrict the mag to 10 rds.

x2 i still like mine, and would like to buy more mags, would love to know if anyone has tried .40 s&w mag in a 9mm? some pistols in 9mm function fine with .40 mags, and allow more 9mms to be loaded

The frames for the 9MM & 40Cal are exactly the same. The M&P was designed firstly around the .40cal. Yes for those who like to load 12 rounds of 9MM in .40 mags it will work or at least it does with my 40 mags.
