If I'm hunkered down with my family in the master bedroom, and a guy is trying to kick his way in, what should I do? I vote shoot through the door.
Just wana point out this could get you thrown in jail. We specifically covered this during my certification course a few years ago. Unless the guy is shooting at you through the door himself you cannot shoot at someone through a closed door. But hey if you get chased into a room by a guy with a gun or knife and hes trying to knock the door down, most people would be hard pressed not to shoot.
as for my 9mm round of choice, I like Gold Dots by Speer. I use them in my .380 too.
