Description
The RM1C is the debut pistol from Rost Martin, a veteran-, minority-, and female-owned firearms company based in Dallas, Texas, and it makes a strong first impression. Sized right alongside the Glock 19 at 7.1 inches overall and weighing in at just 21.1 ounces with the flush magazine, it sits in that sweet spot where a pistol is comfortable to carry but capable enough for the range, home defense, or duty use. This Davidson's-exclusive OSP package takes things a step further by adding a factory-mounted Crimson Trace CTS-1500 red dot, so you're walking out with a fully configured, optic-ready setup from day one.
What Makes the RM1C Stand Out in a Crowded Field
Rost Martin clearly paid attention to what people actually want from a compact 9mm. The 4-inch barrel is hammer-forged and target-crowned for out-of-the-box accuracy. The slide gets a Tenifer treatment for serious corrosion resistance. Atop the slide, you'll find anti-glare serrations that cut down on eye fatigue when you're trying to find your front sight fast. The trigger is a flat-face design with a short reset and a clean break right around five pounds, and the entire controls layout is fully ambidextrous, not just a reversible mag release but true ambi slide stop and magazine release on both sides. That's a level of thoughtfulness that a lot of established brands still don't bother with. Three interchangeable backstraps let you dial in the fit regardless of hand size, and the undercut trigger guard paired with the extended beavertail lets you ride the gun high for better recoil management.
The CTS-1500 Package and the RM1C's Optics Story
The included Crimson Trace CTS-1500 is a compact open-emitter red dot with a 3 MOA dot, a 20,000-hour battery life, and automatic brightness adjustment based on ambient light conditions. It mounts on the Shield RMSc footprint, and the RM1C's optics system supports additional plates for RMR, Docter, Leupold DPP, and other popular footprints, so swapping optics down the road is straightforward. The steel guide rod, steel dovetail-mounted backup sights, and a three-slot Picatinny rail for weapon lights round out a package that's genuinely ready for real use without a trip to the aftermarket. Mec-Gar builds the included steel-body magazines, and CZ P10 mags are also compatible if you need extras. Holster support is solid too, with fits available from ANR Design, Blackpoint Tactical, Crossbreed, DeSantis, and others. The whole thing is covered by Rost Martin's lifetime warranty.

Frequently Asked Questions
Does the Rost Martin RM1C come with the red dot already mounted?
Yes, this specific OSP Compact package ships with the Crimson Trace CTS-1500 factory-installed on the slide. It uses the Shield RMSc footprint and features a 3 MOA dot with automatic brightness adjustment and a 20,000-hour battery life, so it's genuinely ready to use right out of the box.
What holsters fit the Rost Martin RM1C?
Holster support for the RM1C is solid and getting better all the time. Brands like ANR Design, Blackpoint Tactical, Crossbreed, and DeSantis all offer direct fits. Because the RM1C dimensions are very close to the Glock 19 and AREX Delta Gen.2 M, holsters made for those platforms will often work as well, though you should always verify the fit before carrying.
What magazines are compatible with the RM1C?
The RM1C ships with two steel-body magazines made by Mec-Gar, a 15-round flush-fit and a 17-round extended. Rost Martin also confirms compatibility with standard CZ P10 magazines, which are widely available and affordable. Spare RM-branded magazines are also sold directly through Rost Martin.
How does the RM1C field strip compared to other striker-fired pistols?
Field stripping is familiar and tool-free, similar to the process most Glock owners already know. One notable improvement is that you do not need to pull the trigger to release the striker before removing the slide, which is a safer and more intuitive approach than what some competing designs require.
Can other optics be mounted on the RM1C beyond the included CTS-1500?
Absolutely. The RM1C's optics-ready slide supports multiple footprints via metal adapter plates. The RMR plate that also ships with the gun is compatible with the Trijicon RMR and SRO, Leupold DeltaPoint Pro, Holosun 407C, 507C, 508T, 509T, and EPS, plus the Swampfox Kingslayer and Justice series. Additional plates are available through Rost Martin.
Is the Rost Martin RM1C a reliable pistol for everyday carry or defense use?
Based on multiple independent reviews, the RM1C has earned a strong reputation for reliability. In extended testing, it ran everything from budget 115-grain ball ammo to 124-grain +P hollow points without malfunctions, and it cycled cleanly even under less-than-pristine maintenance conditions. The low bore axis and hammer-forged barrel also contribute to consistent, accurate shooting across a range of ammunition types.
