The Rost Martin RM1S pistol in 9mm and black, built to California-compliant specifications (brand part no. RM1SBLKOSP10CA-P), is the subcompact sibling to the RM1C, giving shooters in restricted-capacity states an even more concealable striker-fired option. Rost Martin builds the 3.6-inch barrel pistol with a serrated slide cut for a direct-mount optic, and iron sights back up the mounted red dot. The 10-round capacity is configured for compliant-state carry. Among California-compliant semi-auto handguns, this RM1S configuration favors compliant-state concealed carry.
