Description
The Rost Martin RM1S is the subcompact member of the RM1 family, built for comfortable everyday carry without giving up shootability. This California compliant 9mm pairs a 3.6" match-grade barrel with a Nitron-finished steel slide that is cut for RMR-footprint red dots, so you can add an optic now or later. A flat-faced trigger, aggressive front and rear serrations, and fully ambidextrous controls make it equally friendly for right- and left-handed shooters.
The textured polymer frame includes interchangeable backstraps, a funneled magwell and a Picatinny accessory rail for a compact weapon light. At under 20 oz and 1.10" wide, the RM1S is easy to conceal and easy to shoot well. Pick up your Rost Martin RM1S at Brute Dynamics in Thousand Oaks, CA, where our team will handle your DROS and help you choose an optic and holster.
