My best and probably cheapest S&W .44-40 DA topbreaks. Got it cheap on GB auction due grips broken up. I had a pair chipped K-frame pearls. An easy re-fit, top curve fits, the screw hole is OK so I reset the locating pin hole and trimmed/polished the periphery. About 90% gun, EXC bore. Finding one of these with nice original blue is a rarity.
