The Rost Martin RMS1 in Black is a striker-fired 9mm pistol with a 3.6-inch barrel and a compact frame. The black polymer frame carries a matte black finish, and the slide is optics ready. Ambidextrous controls and an accessory rail are part of the build. The package lists one 12-round and one 15-round magazine, giving two capacity choices in one box. This listing shows the condition as used, while the supplier text calls the pistol new and uses a stock photo, so both descriptions are kept here.

A 3.6-inch barrel places this pistol in the compact group, which suits a shooter who wants a smaller 9mm for everyday handling. The optics-ready slide lets you add a red dot without changing the frame, and the accessory rail leaves room for a light. Two magazines in the box mean a spare is on hand from the start. The black frame and matte finish keep the pistol's appearance consistent from grip to slide.
