Product Description

he Rost Martin RM1S is a purpose-built subcompact 9mm engineered for everyday carry without sacrificing performance. Built around a 3.6" hammer-forged, rifled barrel and a rugged nitrocarburized (Tenifer®) slide, the RM1S delivers match-grade features in a pocketable footprint.

Designed with modern carry ergonomics in mind, the RM1S increases grip grit and surface area for superior control on a smaller frame. A sub-5 lb flat-face trigger with an extra-short reset and crisp break helps you get fast, consistent follow-ups. The RM1S ships optic-ready with an RMR cut and accepts the most popular red-dot footprints (metal adapter plates available from Rost Martin). Additional features include aggressive front/rear slide serrations, non-glare top slide serrations, fully ambidextrous controls, a funneled magwell for faster reloads, modular backstraps, and textured index points to aid recoil management.

Each RM1S includes both a 12-round flush magazine and a 15-round extended magazine for selectable 12+1 or 15+1 carry. Lightweight, tough, and made in the USA, the RM1S is ideal for concealed carry, backup use, or anyone who wants subcompact performance with full-featured ergonomics.
