I just inherited 2 pistols. One is a S&W model28-2 357 mag, and the other is a S&W model 58 41mag. At least that is what is stamped in side of the crane. But this pistol has some of the model 58 features and some model 57 features. It has no ejector rod shroud, but has a frame that is the same size as a Model 29, and it has adjustable sights, which the 58 did not have. Did S&W ever make the 58 with adjustable sights, or the 57 without the ejector rod shroud?
