S&W M&P mag falling out?

[Sir Jake]

I shoot a "fun" tactical shoot at my local club every week (there are 5 of us that shoot M&Ps for this, 9's, 40's & 45). I do the ultra fast "robo cop" reloads, where if you slam a mag in hard enough it drops the slide and chambers a round for you.

That's what robo cop reload is.
