Texas-based Rost Martin threw its hat into the self-defense handgun market last year with its striker-fired, polymer-frame, compact 9 mm Luger RM1C handgun, a pistol loaded with both features and value. New for 2025, the company is adding two new additions to its lineup with the RM1S and RM1C Comped.
Built around a 3.6” barrel, the Rost Martin RM1S has both a shortened slide and frame. As compared to the company's previous RM1C, overall height has been reduced by 0.6” to 4.4” and length by 0.38” to 6.78”, with a weight of 19.76 ozs. By shortening the length of the frame’s dustcover, the RM1S loses one of the three accessory slots found on the RM1C. Extra texturing is added to the grip area to provide plenty of purchase. Two magazines are supplied—one 12-round flush-fit magazine and one extended 15-round magazine. Like its larger sibling, the RM1S is optics-ready with a plate provided for mounting sights with an RMR footprint. Mounting plates for other footprints are available as accessories.
The RM1C Comped takes the RM1C pistol introduced last year and adds an integral compensator to its 4” barrel, with a matching port in its slide, a feature the company claims reduces recoil by 25 percent. It has the same dimensions as the original, with an overall length of 7.1”, a height of 5”, a width of 1.1”, and weighs 21.1 ozs. It comes with one 15-round flush-fit magazine and one 17-round extended magazine. The compensated slide and barrel are also offered as an accessory for those who already own an RM1C.
The Rost Martin RM1S has an MSRP of $469 and the RM1C Comped retails for $489. Both new pistols are compatible with standard RM1C holsters. Additionally, the company recently announced that standard RM1C pistols will be available with HIVIZ LiteWave H3 tritium sights with an MSRP of $489.
