I prefer a compact (or midsize) handgun for concealed carry. I'm willing to give up a (little) bit of concealabilty, over the subcompacts, in exchange for the added comfort and control afforded by having all of my fingers on the grip ( not to mention the additional one or two round capacity increase). My brother, on the other hand, takes the position that a concealed carry handgun is carried far more than it is shot, so he wants the smallest, lightest subcompact he can find. I can understand the merits of both positions. What puzzles me is why a person would buy the smaller gun, but then add an extended magazine, usually with a special baseplate, that increases the length of the grip back to that of the next size larger pistol anyway. Ditto the oversized rubber finger groove stocks on compact J- frame revolvers. Since I carry IWB anyway, the 0.5" difference in slide length is irrelevant to me. So, what is the advantage?
