The Springfield Armory XD-45 Service Model features a 4.0-inch barrel [1] and is a highly respected, polymer-framed striker-fired pistol chambered in .45 ACP. First introduced as a duty weapon, it is famous for packing a massive double-stack magazine capacity into a highly ergonomic frame that mimics the natural grip angle of a classic 1911 pistol.
