EAA Girsan MC1911S Influencer .45 ACP | 5″ Barrel

The EAA Girsan MC1911S Influencer is a full-size 1911-pattern pistol chambered for .45 ACP with a 5-inch barrel and an optic-ready slide cut for common RMR footprints. It pairs practical 1911 ergonomics—extended beavertail, checkered grip and a mag well—with features such as an ambidextrous safety and adjustable iron sights. For red-dot use on this platform, an optic such as a Trijicon RMR is a reliable choice and falls well under $1,000.

Its configuration and controls make the MC1911S suitable for range training and competitive target work where a full-size .45 platform and comfortable sights are valued.
