ZellerSC, that's a surprise. Those heavy barrels on the 65 3" guns look real heavy. I wonder if some of the weight difference is because of the square vs. round butts?
My 4" Pre-Model 10 and my 4" Victory revolvers each weighs 30 ounces - as does my 4" Model 64 (stainless version of the same gun). My 3" Model 65 weighs in at a hair over 32 ounces.
