Stainless Chief 60 .38, loaded with NYPD load (135 grain JHP). Worked for them, should be fine. I don't like to over-think things. I carry an additional 5 round in a Bianchi speed strip.
I got laughed at by this guy from Texas once when he asked me how much 'gun' do I carry. I said typically a P30SK with 10+1 and a spare 10 in a pocket. The guy carries a Glock 48 on his hip and then a P226 with TLR-1HL in his backpack and 4x spare free state mags with that in there. The point was he would engage threats with the 48 first, and then when he had time, to whip out the larger gun for extended engagements. Seriously? Then again there are other guys on here who are probably comfortable throwing a 642 in a pocket and go out the door. What do you guys typically carry and how much spare booletz?
