The Rost Martin RM1X CA-Compliant Compact (brand part no. RM1CXBLKOSP10CA) is a 9mm striker-fired pistol built to meet California’s roster requirements while keeping the features that put Rost Martin on the map — a 4-inch black match-grade barrel, an optic-ready slide, and a value price from the Dallas, Texas maker. Rost Martin machines the slide from nitrocarburized steel with serrations front and rear, and the black polymer frame carries a Picatinny accessory rail and interchangeable backstraps for a tailored grip fit. Capacity is capped at 10+1 for restricted-state compliance. Among semi-auto handguns, the RM1X favors California shooters who want a modern optic-ready compact without a restricted-feature compromise elsewhere in the gun.
