Works well in my maxp. fatboy - Maxpedition Sneak Holster Insert w/ Mag Retention, Black

My full size M&P 9 2.0 and Glock 43 work well with this insert. It's very nice that both the gun and spare magazine stay upright and ready for action now. Well worth the money. The only reason I'm not giving it five stars is that it'd be nice if it was a little more adjustable.
