Product Overview

The Rost Martin RM1C Compensated 9mm is a modern striker-fired pistol engineered for the serious shooter who demands performance without compromise. Built around a robust 4-inch barrel and a high-capacity 17-round magazine, this handgun integrates a factory-machined compensator to significantly reduce muzzle rise and felt recoil. This package is further enhanced by the inclusion of a Viridian RFX11 red dot sight, four total magazines, and a versatile 15-round magazine option for maximum flexibility. Designed for duty, competition, and advanced personal defense, the RM1C is for shooters who prioritize flat shooting, rapid follow-up shots, and a ready-to-run configuration straight from the case. It represents a complete system, not just a firearm, tailored for those who value practical accuracy and speed.

Key Features

• Integrated Barrel Compensator: The 4″ barrel features a precision-machined compensator with top ports that redirect gases upward, actively countering muzzle flip. This results in a flatter shooting experience, allowing for faster sight recovery and tighter shot groups during rapid strings of fire.
• Optic-Ready with Viridian RFX11: The slide comes cut for a red dot footprint and is shipped with a Viridian RFX11 optic pre-installed. This green dot sight provides a crisp, highly visible aiming point for rapid target acquisition, eliminating the need for a separate purchase or milling service.
• Enhanced Capacity & Flexibility: The package includes four magazines total: two 17-round flush-fit magazines for full capacity and two 15-round magazines with a finger rest baseplate for a customizable grip. This offers immediate logistical and ergonomic advantages for training or deployment.
• Ergonomic & Durable Frame: The polymer frame is designed with an aggressive texturing pattern on the grip and under the trigger guard, ensuring a secure hold in all conditions. A reinforced steel chassis provides a stable foundation for the fire control group, contributing to consistent trigger feel and long-term durability.
• Performance Trigger System: Features a flat-faced trigger with a clean take-up, a defined wall, and a crisp break. The design minimizes pre-travel and overtravel, giving the shooter precise control for both deliberate aimed shots and controlled rapid fire.
• Robust Defensive Sights: Co-witnessing suppressor-height iron sights are installed, allowing for an immediate backup aiming solution should the red dot become inoperative. The front sight features a high-visibility dot for quick indexing in low-light scenarios.

Performance & Applications

The Rost Martin RM1C’s compensated design and optic-ready system make it exceptionally capable in specific, demanding roles. Its configuration solves real-world shooting challenges, offering tangible benefits in these scenarios:

For the action pistol competitor, the RM1C is a turnkey solution for divisions that allow compensators and optics. The reduction in muzzle climb is immediately noticeable when transitioning between multiple targets or managing doubles on steel. The flat shooting characteristics allow the shooter to maintain a clear sight picture through the Viridian dot, leading to faster, more confident hits. The included magazine set provides all the necessary spares for most stage plans, making it a complete competition-ready package from day one.

As an advanced home defense or duty firearm, the system offers significant advantages. The compensator’s recoil mitigation is not about reducing power, but about enhancing control, especially in high-stress situations where shot placement is paramount. The red dot sight simplifies the aiming process, allowing the eye to focus on the threat while superimposing the dot. This can lead to more accurate shots under pressure. The high magazine capacity, bolstered by the three included spares, provides a substantial level of readiness.
