The Springfield Armory RoninA(R) AOS 4.25" in .45 ACP delivers full-power 1911 performance in a lightweight, carry-ready Commander-size package that tips the scales at just 29.5 ounces. Built around a forged aluminum alloy frame with satin aluminum Cerakote and topped by a deep hot-salt blued forged carbon steel slide, this two-tone beauty pairs classic 1911 lines with modern reliability and corrosion resistance. The match-grade 4.25" hammer-forged stainless steel barrel, fully supported ramp, and traditional GI-style bushing system guarantee the smooth function and pinpoint accuracy that have defined the 1911 platform for over a century. Agency Optic System (AOS) collaboration brings true drop-in optics compatibility to the Ronin lineup-modular plates accept today's most popular red dots including RMR, Shield RMSc, Delta Point Pro, and Docter while retaining a low-profile co-witness with the fiber-optic front and serrated black rear iron sights built into every plate. Every Gear-Up model ships factory-equipped with the ultra-compact Viridian RFX11 green dot sight featuring Instant-On technology and an impressive 30,000-hour battery life, giving you an out-of-the-box running optic that's bright, fast, and always ready. Complete with four 8-round magazines, handsome Crossed Cannon wood laminate grips, and a padded nylon range bag with dedicated storage compartments, the Ronin AOS 4.25" .45 ACP is the ultimate blend of timeless style, everyday carry comfort, and cutting-edge performance.
