The Ruger RXM is a 9mm striker-fired pistol built around a removable serialized stainless steel Fire Control Insert housed in an interchangeable Magpul Enhanced Handgun Grip. This design supports future grip-frame customization while retaining compatibility with many Gen 3-type pistol holsters and accessories. Its Magpul grip features 3/4-scale TSP texture, indexing pads, a flared magazine well, trigger guard undercut, beavertail, magazine release scallop, and a universal-pattern accessory rail. The slide supports direct mounting of RMR, DeltaPoint Pro, and RMSc pattern optics. Co-witness-height steel sights include a tritium night front sight for a clear sight picture with or without an optic. A flat-faced trigger provides a smooth pull and tactile reset, while the integrated trigger safety, internal striker blocker, and chamber inspection port add practical handling safeguards. The pistol includes two 15-round Magpul PMAG 15 GL9 magazines and a co-branded plastic carry case.
