Rost Martin RM1S Comp 9mm Subcompact Optic Ready

Rost Martin RM1S Comp: Concealment Meets Capability

The RM1S Comp represents a thoughtful approach to subcompact pistol design—a firearm engineered for those who refuse to compromise between concealability and shootability.

Design and Engineering

This striker-fired 9mm features a 3.6-inch crowned, hammer-forged match barrel paired with an integrated compensator that works to reduce felt recoil and muzzle rise. The result is a compact platform that helps you stay on target with speed and accuracy, even in rapid-fire strings.

Ergonomics and Control

Rost Martin has equipped the RM1S Comp with features that enhance control and handling:

• Ambidextrous controls for shooters of any hand preference
• Modular backstraps to fit various hand sizes
• Textured index points (gas pedals) on both sides of the frame to aid recoil management
• Oversize undercut trigger guard and extended beavertail for superior recoil control
• Funneled magazine well for faster, more intuitive reloads
• Responsive grip texture for secure purchase in all conditions

Sights and Optics

The compensated slide features top anti-glare serrations that provide clear sightlines and steady control in any lighting. The pistol ships optic-ready with an RMR optics plate included, allowing you to mount your preferred red-dot sight.
