So I'm still trying to figure this out.. I know that S&W normally stands for Smith and Wesson.... But it wouldn't make any sense to me if you had an XD .40 S&W (Smith & Wesson)... To me that's just a contradiction... Also why are the round for my 9mm called Luger? I know Luger is a manufacture (or used to be... not sure if they still are in business).... Maybe I'm still green, but can anyone help me out here....???? Thanks!
