How much are you going to shoot it and how often are you going to shoot heavy loads?
My favorite .44 Special is a 329PD. It is uncomfortable to shoot with .44 Magnum loads, but great with .44 Special level loads.
I have had 4" 625 and 629 MGs and found the 625 easier to shoot with heavy loads.
Well I’ll be handloading for it, so will cook up some reduced loads for shooting fun, and make up some heavy stuff for pig and backpacking.
I’ll check out the 625 as well as the suggested Mountain gun, which if memory serves me, is a pretty light revolver, made to carry.
