I personally like the Ruger SA revolvers. The weight is OK to carry. Watch heavier guns as they are much less fun to carry.
The 4 5/8 - 7 1/2 barrels are best for me. I feel I need to match the barrel to most likely shot range. For me, this is roughly:
4.625 25 yds
5.5 50 yds
7.5 75 yds
10.5 100 yds
I like 7.5 or smaller in a hip holster. I carry cross draw for hunting.
44 mag is a good round, especially in factory loads. I prefer 454 Colt in my own loads.
The SR3 frame feels good to me, but max loads might make the Bisley better.
I hunt with the Bisley Blackhawk in 45 Colt. 265 gr at ~1300fps.
