I used to use my 5" 625 before they changed the rules to 4" max. Now its one of several depending on what I feel like playing with on any particular day. It might be a 4" 586 out of a Kydex holster if I'm trying to be competitive, a 4" Model 10 out of a leather OWB because I like the back to basics aspect, a 3" Model 13 out of a leather IWB because it is one of the more truly practical carry guns that I own, and I've even shot matches with a 4" 629 out of either an IWB or a thumbreak OWB loaded with the Skeeter load and HKS speedloaders to get trigger time with a great woods gun. I don't feel poorly equipped with any of them!
