The Rost Martin RM1F 9mm OR 4.5" 10rd CA is a full-size, striker-fired pistol built for dependable performance and confident handling. Its 4.5-inch hammer-forged match barrel, optics-ready nitrocarburized steel slide, and deep front and rear serrations work together to deliver consistent accuracy and easy manipulation. Fully ambidextrous controls and Rost Martin’s responsive grip texturing make the RM1F comfortable for a wide range of shooters.

This California-compliant model offers a 10-round capacity, magazine disconnect safety, and loaded chamber indicator while remaining well suited for range practice, training, and general defensive use. The flat-faced trigger with extra-short reset supports precise shot control, and the included RMR optics plate lets you add a red dot when desired. Thoughtful ergonomics, modular backstraps, and a funneled magwell reflect Rost Martin’s focus on practical innovation and modern craftsmanship.
