The Rost Martin RM1C Comp pistol in 9mm with a 4-inch match barrel (brand part no. RM1CBLKOSP10CA (COMP)) is purpose-built for California compliance, listed on the California DOJ roster while retaining the RM1C’s precision engineering. Rost Martin integrates a compensator into the barrel for reduced recoil and improved accuracy, and the optic-ready, serrated slide includes an RMR optics plate. A flat-face trigger with a short reset pairs with slide-top anti-glare serrations, and ambidextrous controls with modular backstraps ensure a comfortable fit. Two 10-round magazines ship with the pistol to meet California’s capacity requirements. Among California-compliant semi-auto handguns, this RM1C Comp configuration favors California shooters who want a compensated, optic-ready compact pistol.
