The Rost Martin RM1CX 9mm Pistol (brand part no. RM1XBH) is a striker-fired semi-auto handgun built by Rost Martin for shooters who want a full-capacity duty-size pistol with a modern optics-ready slide. Finished in black, it runs a 4-inch barrel and holds 19+1 rounds, giving it the capacity and balance of a serious duty or home-defense pistol. The optics-ready slide cut lets shooters mount a red dot directly for faster target acquisition, while the factory front sight keeps the pistol usable as a co-witnessed backup or standalone iron-sight setup. It’s built for shooters who want a modern, capacity-forward 9mm platform without compromise.
