Can anybody tell me what does it mean? Oh this is for the S&W revolvers. Is it better without the dash or something? Sorry for the noob question.
Exactly what I was thinking.
So the higher the number, the more changes they did to the gun?The dash is later versions of the same gun. Minor changes were made with each successive dash. For example -1 they may change the firing pin, -2 changed a spring, etc.
Also depending on the exact model, the no dash can usually have the lowest production numbers, thus being the rarest revision.
