I have a 1962 or 63 vintage S&W model 28-2 that was converted to 357/44 Bain & Davis wildcat at some point in its life. Since I got it earlier this year, I have fitted a later 357 cylinder so I now have a "convertible" model. If the N frames will stand up to a 44 magnum that has been necked down to 357 & pushes a bullet out at around 2,200 FPS, I am pretty sure it will hold up to any 38 , +p or 357 loads.

By the way, does anybody know when S&W quit beveling the front edge of the flutes and marking serial numbers on their cylinders? The spare cylinder I have has sharp edges on the flutes and no s/n or assembly numbers, but the chambers are recessed. Thanks, John
