Top Concealed Carry Firearms You Can Trust
Trust is everything when it comes to a concealed carry firearm. You need to know — without hesitation — that your pistol will perform exactly as expected every single time.
At Rost Martin, we are a minority, Veteran, and female-owned company based in Dallas, Texas — in development since 2020 with a single goal: expand Second Amendment personal freedoms and rights to the next generation of gun owners. The RM1 Series was engineered around readiness, precision, and trust — built to be the concealed carry firearm you never have to think twice about.
This guide covers the full RM1 Series lineup, what sets each model apart, and how to find the right concealed carry firearm for your needs.
What Makes a Concealed Carry Firearm Trustworthy?
A concealed carry firearm earns trust through consistent performance — not marketing claims. Here is what the RM1 Series is built on.
Match Barrels Standard
Every RM1 Series pistol ships with a crowned match-grade barrel as standard. The RM1C and RM1C Comp feature a 4-inch barrel. The RM1S features a 3.6-inch barrel. Match-grade barrels deliver enhanced accuracy and consistent performance across thousands of rounds.
Optic-Ready From the Factory
All RM1 Series pistols ship with an optics-ready slide and a metal RMR plate installed. Any optic with an RMR footprint mounts directly — no gunsmithing, no additional cost, no waiting. Additional optic plates for other footprints are available at .
Fully Ambidextrous Design
Every control on the RM1 Series is ambidextrous — designed for left-handed and right-handed carriers equally. This is not an afterthought or an upgrade. It is standard on every model.
Custom Ergonomics
The Responsive Grip Texture™, modular backstraps, textured index points (“gas pedals”), and extended beavertail work together to give every shooter — regardless of hand size or experience level — a secure, confident grip. The RM1S features a deeper grip texture pattern than the RM1C, tuned for its shorter grip circumference.
Responsiveness Under Pressure
All RM1 Series pistols feature a flat-face trigger with extra-short reset. The RM1C’s 5.0 lb pull is lighter than the RM1S and Comp’s 5.5 lb — both engineered for faster, more controlled follow-up shots when it counts.
The RM1 Series: Top Concealed Carry Firearms
RM1C — Compact Performance Without Compromise
Best for: All-day IWB or OWB carry, maximum capacity, versatile wardrobe

Carrying 15+1 in the standard configuration and 17+1 with the extended magazine, the RM1C gives you serious firepower at 7.1 inches overall and 1.1 inches wide. Available in Black, FDE, Stone Gray, Green, and Mojave. MSRP $469.00.

RM1C California Compliant — Fully Equipped, State Compliant
Best for: California and other restricted-state residents
The RM1C California Compliant delivers every feature and performance characteristic of the standard RM1C while meeting California’s specific regulatory requirements. Every premium feature remains intact — only the capacity is adjusted to comply with state law.
Capacity is 10+1 with a 5.5 lb trigger pull. Available in Black, FDE, Stone Gray, and Green. MSRP $489.00.

RM1C Comp — Compensated Carry, Controlled Recoil
Best for: Recoil-sensitive carriers, high-round-count training, rapid engagements
The RM1C Comp adds an integral compensator to the proven RM1C platform. As the bullet exits the barrel, expanding gases are redirected upward — creating downward pressure that significantly reduces muzzle rise and felt recoil. The result is faster, more accurate follow-up shots without any aftermarket modification.
Unlike bolt-on compensators, the integral design ensures optimal gas flow and reliability. Available in Black only. MSRP $489.00.
Key Features:
- Integral compensator for reduced muzzle rise and felt recoil
- Crowned 4-inch match-grade barrel

RM1S — Subcompact Power with True RM1 DNA
Best for: Deep concealment, appendix carry, lighter clothing, smaller frames
The RM1S is Rost Martin’s subcompact concealed carry firearm — purpose-built for carriers who need maximum concealability without giving up the features that make the RM1 Series trustworthy. At 6.2 inches overall and 19.76 oz empty, it carries discreetly under virtually any clothing. The RM1S has been independently reviewed by Guns & Ammo and The Truth About Guns.
The RM1S features a deeper Responsive Grip Texture™ than the RM1C, tuned specifically for the shorter grip circumference. Standard capacity is 12+1, with a 15+1 extended magazine available. Available in Black, FDE, Stone Gray, and Green. MSRP $469.00.
Key Features:
- Crowned 3.6-inch match-grade barrel
