Everything about the M&P 45 is used. Including the two spare magazines I ordered on line. I only run cheap practice ammo through it, because I like to come out here and shoot. I don't feel in any way inferior for having the limitation of ten rounds of 45. The inherent advantage of any semi-automatic over a revolver is reloading speed, in my opinion. But other semi-autos have given me problems - not this one though.
