I am about to start buying .40 ammo for carry purposes (my CHL finally came in). I would have bought a few days ago when my CHL came in -- but my closest supplier was out of all .40. (I know, the ammo shortage goes on and on). I plan to go to a bigger store later this week. They have always been stocked so far. Those of you who carry a .40 -- what do you carry for protection? I have also heard of some folks mixing FMJ with JHP in a carry mag to have some penetrators. Does anyone on this forum recommend that? If so, what about danger from over-penetration?
