drboom: I’m personally a Smith guy when it comes to wheelguns, but I had a Ruger GP100 in 4″ for a while. Great gun, and, typical of Ruger revolvers, was built like a tank. I remember shooting really hot 125gr JSPs out of it and the gun handled them without a problem.
I’ve got a Smith 629 4″ in .44 now and it’s fun to do the one-handed Hollywood thing, especially with some 240gr Hydra-Shoks.
