The RM1S is constructed with a durable polymer frame finished in black and enhanced by a responsive grip texture that promotes secure control during recoil. Its striker-fired action is paired with a flat-face trigger, providing a consistent press and predictable break. Fixed sights include a black serrated rear sight and a front dot for fast and intuitive sight alignment. This model features an optics-ready slide and includes a Viridian RFX11 red dot, expanding capability straight out of the box. Ambidextrous slide and magazine releases support both right- and left-handed shooters, while the absence of a manual safety keeps operation simple and intuitive. With four included magazines, the RM1S is well suited for carry, training, or defensive applications.
