The Rost Martin RM1F OR/FS is a 9mm semi-automatic pistol with a 4.5-inch barrel and a 10+1 capacity. It ships in an optics-ready configuration with fiber-style sights, giving shooters a factory red-dot mounting option paired with a fast sight picture for aiming without an optic mounted. The compact frame suits both everyday carry and range use, and the platform is built around everyday reliability rather than a specialized competition role.
