So this 642 is my first S&W. I have a GP-100 and have had a Security Six and SP-101 and have always been biased towards them until today. Not to say I don't love the GP-100 but I have a new found respect for S&W revolvers. It's like comparing a Clydesdale and a Tennessee Walker. I know the Ruger will work after being hit by a cruise missle but the Smith has an elegance to it's looks and mechanics that is inspiring even to a ruger fan.
