ASP. For those who may not know. John Correia of Active Self Protection, who watches thousands of defensive use videos, and posts many, stated that he has never seen a non-law enforcement reload during a defensive shooting.
Something to think about when deciding 5-6 or 10-12+. Having said that I am quite comfortable carrying my 638, and don't feel under gunned in the least. Truth of the matter is I don't shoot small auto well unless they are in small calibers, And I won't carry a large auto no matter how much I want to or should. Be prepared for zombies, ninja death squads, comforting not comfortable be darned. It's a J-Frame 100% of the time or maybe/maybe not auto I can constantly hit with.
