The Springfield Armory 1911 Ronin pistol in .45 ACP with a 5-inch barrel (brand part no. PX9120LAOSPAC) delivers the full-size classic 1911 platform in its original chambering, built for shooters who want traditional stopping power with modern manufacturing tolerances. Springfield Armory machines the barrel with a 1-in-16 rate of twist, and the optic-ready slide is serrated front and rear for a secure grip during manipulation. Adjustable sights combine a fiber optic front with a U-notch rear for precise aiming, and a beavertail safety rounds out the traditional 1911 controls, with four 8-round magazines included. Among full-size 1911 semi-auto handguns, this 1911 Ronin configuration favors traditionalists who want the original .45 ACP chambering.
