6" 19s are very desirable. I have a blue 6" 19-3 which is a very good shooter. I shoot mainly .38 Specials and load them light. Not a lot more recoil than a .22. They will take a lot of .357, but the common wisdom is to stay away from 125 gr hot loads. 140 gr and above are preferred. I load 158 gr for any .357 shooting.
