OK, that sounds like a line out of the movie "Marathon Man" which put the fear of dentists in me for years. lol Just picked up a stainless 4" K frame .38Spl. Wondering if a cylinder from a stainless K frame .357 would fit in it, and if so, would it be safe to fire .357's in that frame? I know I can just buy a .357, just curious about this though, and to find out if anyone has done it. If it's not feasible, a simple no would be appreciated, safety lecture not required.
