The Ruger RXM 9mm is a modern, optic-ready semi-auto pistol that blends the reliability hunters, range shooters, and concealed carriers look for with the adaptability of a Magpul Enhanced Handgun Grip in OD Green; the removable serialized stainless steel Fire Control Insert (FCI) sits inside the interchangeable EHG so you can configure the pistol to your needs while retaining a Gen 3-compatible footprint for holsters and off-the-shelf parts. Chambered in 9mm Luger with a 4" precision rifled alloy steel barrel finished in black FNC nitride and a 1:10" RH twist, this striker-fired handgun delivers a flat-faced trigger with a tactile reset, extended magazine release, raised slide stop, and an undercut trigger guard and beavertail that promote a high grip for better control during follow-up shots. The slide accepts RMR DPP and RMSc pattern optics and co-witness steel sights with a tritium front for low-light work, while the low-profile flared magwell and textured 3/4-scale TSP surface aid quick reloads and secure carry. Weights, dimensions, safety features, and the requirement for an FFL transfer make this Ruger RXM a practical choice for duty, range training, and everyday carry-minded owners.
