I believe I saw a statement in a recent topic thread that said that the short-framed Detective Special was perhaps not as strong as the pre-1966 models and also that the later models with enclosed ejector rods were the strongest. I can't really see that the grip frame size would materially affect the strength or durability of the revolver. I also read somewhere in the Colt Forum (or perhaps it was the S&W forum) that Colt warranted all of its .38 Special chambered revolvers for use with .38-44 ammunition back in the 1930's. Any thoughts on this? It's an academic question for me as I wouldn't be shooting heaping piles of hot .38 Special ammunition through any Detective Special.
