Rost Martin RM1S Comp 9mm | 3.6-inch Barrel

The Rost Martin RM1S Comp is a striker-fired subcompact pistol built for discreet carry and controlled follow-up shots. It features an optics-ready slide with an RMR plate, a 3.6-inch hammer-forged barrel with an integrated compensator, and a polymer frame for reduced weight. This configuration is suited to concealed carry and routine range training where manageable recoil and quick sight acquisition matter.

Recommended optic: the Trijicon RMR Type 2 is a robust, purpose-built red-dot that pairs well with the RM1S and is available well under $1,000.
