I have the Ruger GP100 with the 4" barrel. Got it in 1994 and it has been a trusty road companion. Built like a tank, it will outlast me and all my descendents.
I also treasure the S&W 686P, 2.5" barrel. Even though it comes in at about 40 oz. loaded, with my Kramer IWB holster and a tough belt, CC is easy and discreet with a loose fitting shirt.
I MagnaPorted the barrel, did a action job and switched to Pachmayr grips.The best trigger on any revolver I own. Like butter.
Bought it in 1998. I'll never sell this one.
