personally I prefer either Double Action Only, or Single Action Only. never really cared for the DA first shot, SA thereafter. I always throw the first 2 shots like crazy. I think the p220 is the only Sig I've handled, can't remember it was about 3 years ago, I loved it and if I had 800 bucks for a good used one I would have one. You won't really go wrong with a SIG, whichever model you pick.
