I think we should say a bit more about ammo appropriate for callmike2's gun, which would be chambered for the .32 S&W. The cartridge known as the .32 Short Colt (at left in the pic) is not identical with the .32 S&W (right in the pic). The Short Colt has a case of smaller diameter, and its rather long, outside-lubricated bullet usually prevents it from chambering in a gun cut for the .32 S&W. The Short Colt will, however, chamber in a .32 S&W Long chamber, but firing would probably result in split cases and cannot be recommended. I think I am correct in saying that the .32 "Colt New Police" is identical to the .32 S&W Long, except for having a flat nosed bullet, and these, therefore, could not be chambered or fired in a .32 S&W revolver, but would work fine in a .32 S&W Long revolver. The nomenclature of .32s, like a lot of other cartridges, can cause confusion.
