Yea, most of the reviews I found were a few years old too. No one locally carries it either so I was gonna bite the bullet and just order one. Glad I didn't.
hmm I have never seen that before, curious why. Eric's reply sounds logical for the crimps but not very logical if you want your mag to last for anytime before snapping in two.
my M&P mags are also like this, 9 rounds max, no way in hell can i get a 10th round in there. Had to cut a good bit from the follower and a little of the spring. my g23 10rd mags have been fine
