I went out to the range today with my S&W M&P40, and after I fired about fifty rounds, the magazines started to drop out while firing. It varied, but the magazine would usually come unseated every two shots. It happened with all three of my mags regularly, and I'm positive it's not my grip releasing the mags. The mag catch looks okay, no visible damage and the spring seems to have good tension. Anyone have any ideas as to what is going on?
