gp 100
in my opinion i think you got the better of the two. ruger is the only revolver i will buy. ive owned a couple revolvers and like the rugers best. i have a ruger redhawk, 44 mag. which i feel is better than the S&W model 29. ive owned a gp 100 but traded it for the 44. once you start shooting yours i think you will like it.
