I feel your pain, man. N frames just aren't as comfortable for me to handle as K frames are, and I just don't want a 625 because I'm a contrarian. What you may want to do is get an S&W .38 or .357 and shoot it anyway. You probably won't beat any other revolver shooters, but at this point you probably weren't gonna beat 'em yet anyway. If you get a 627, a 686Plus, or any other more than 6 shooter, you also have the option of shooting it in Production. Again you'll be at a disadvantage, but that's how it is.
I, for one, would like to see the USPSA do like the IDPA and have a separate class for revolvers loaded without moonclips, as most 625s are used by competition shooters and there really aren't any other options.
