SUREFIRE designed this can at the request of "door kickers" in the field that wanted a little more "trauma" to their targets when they had to resort to a "muzzle strike" to stun a target down. It's a SUREFIRE MINI, with "teeth" on the front of the endcap (they've named the can the "MINI-MONSTER"). I handled a couple of these this last week and they are ABSOLUTELY BAD AZZ!!!! You can't imagine how "nasty" the can looks until you see it in person. These are gonna be very popular (and of course, we'll have the first one's to hit the street ).
