The Rost Martin RM1S is a subcompact 9mm pistol designed for concealed carry and performance. It features a 3.6-inch hammer-forged barrel and a flat-faced trigger with a short reset, crisp break, and a trigger pull weight of under five pounds. The grip has been enhanced with increased texturing in both grit and surface area, improving control, comfort, and accuracy. A slight beaver tail allows for a higher grip, while front index finger contouring helps shooters better “drive” the pistol for improved handling.
The slide is treated with Tenifer® for durability and corrosion resistance, making it well-suited for varied weather and heavy use. The RM1S includes fully ambidextrous controls, aggressive front and rear slide serrations, a funneled magazine well for faster reloads, and non-glare top serrations. It comes optics-ready with a standard RMR cut and supports other popular red dot footprints, with additional mounting plates available from the manufacturer. A two-slot Picatinny rail allows for attachment of pistol lights.
The CA Rost Martin RM1S OSP is a California Specific Model and is CA-DOJ Roster Approved.
*This California model will include a magazine disconnect safety and loaded chamber indicator.
