I like to carry HP AMMO when I think I will be using my 1911 around crowds. My thought process is that if it only gets 14" of penetration in ballistic gelatin than it wont impose as much a threat to others. When I'm at home, and in the field I carry either HCFN, or JFN in the mag. I was checking out test some years back, and you can more than double the penetration depending on the bullet. Please do not start this into a caliber debate! I am only interested in what others do that carry this cartridge, and maybe get some pointers as to the best ammo now a days.
