I just bought a Smith and Wesson safety hammerless at Cabela's because why not? It's a gun with an interesting history behind it (being the model of gun used to assassinate President McKinley in 1901). It is chambered in .32 S&W (sometimes known as .32 short to differentiate it from .32 S&W long). My research seems to indicate that up until 1940, this cartridge was loaded with black powder. However, the serial number seems to indicate that the gun is a late production model. Granted this is not a gun I intend to shoot very often, but I do want to shoot it. Therefore I want to make sure the ammunition I use is safe for the gun. Anyone who has more knowledge of these guns than I do, can you tell me which serial numbers should be safe for use with smokeless?
