When I bought my first semi-auto center fire handgun after finish school, I bought an XD-40. Bought the XD in 40 S&W because I wanted to make Major in USPSA that I intended to start shooting with my new handgun. Little did I realize at the time that the XD-40 (due to its 9mm width magazine bodies) was never going to be competitive in Limited. Nearly 40,000 rounds later I was pretty good in Limited-10 with my XD-40 Tactical and I am fond of 40S&W probably for no other reason than I have shot it a fair amount and it was my first semi-auto handgun cartridge. When I started shooting Revolver division I stuck with 40S&W and bought a S&W 610.
