About this product
The ROST MARTIN RM1C is a compact, striker-fired 9mm pistol engineered for modern carry with a 4-inch match-grade barrel and optic-ready RMR-cut slide. Built around precision mechanics and duty-grade reliability, it bridges the gap between concealed-carry compactness and full-size shootability. I've seen too many shooters compromise on either ergonomics or accuracy—this platform minimizes that trade-off.
What is the ROST MARTIN RM1C used for?
This is a daily-carry 9mm designed for shooters who demand red-dot capability without sacrificing iron-sight performance. The 4-inch barrel provides a 15% longer sight radius than typical 3.5-inch compact pistols, improving accuracy for both defensive scenarios and range training. Combined with the aggressive grip texture and 24-ounce unloaded weight, it maintains controllability during rapid strings of fire.
How does the ROST MARTIN RM1C compare to the Stevens 334 Rifle?
The RM1C offers immediate defensive capability at close quarters where a rifle like the Stevens 334 in .308 Win would be impractical. While the Stevens provides superior long-range ballistics from its 20-inch barrel, the RM1C delivers 9mm rounds on target in under 1.5 seconds from concealment. For home defense under 25 yards, the pistol's maneuverability and 15+1 capacity make it the better choice for confined spaces.
What does it weigh and what are the dimensions?
The RM1C weighs 24 ounces empty and measures 7.2 inches long by 5.1 inches high. The slide width is 1.1 inches, fitting standard holsters designed for Glock 19-sized pistols. At 4.3 inches tall with the flush magazine inserted, it conceals effectively in appendix or strong-side IWB positions without printing under most clothing.
Who is this NOT for?
Avoid this if you require subcompact dimensions for deep concealment—the 4-inch barrel adds nearly an inch over micro-compacts like the SIG P365. Shooters preferring hammer-fired systems or those needing California-compliant configurations should consider alternatives. The aggressive grip texture may also irritate bare-skin carry without an undershirt.
What's in the box?
You receive the pistol, two 15-round magazines, modular backstraps (small/medium/large), a cable lock, and owner's manual. The magazines feature anti-tilt followers and robust springs rated for 5,000+ cycles. Unlike some competitors, Ironclad Armory includes all three backstrap sizes rather than charging extra for customization.
Is the ROST MARTIN RM1C worth it at $466.99?
At this price point, it outperforms entry-level striker-fired pistols by including both optic mounting and premium HiViz sights—features that typically add $150-$200 to base models. Compared to the Stevens 555 Sporting shotgun platform, the RM1C delivers modern defensive handballistics without requiring additional sight upgrades. For shooters moving from irons-only to red-dot readiness, this represents one of the most cost-effective transitions available.

Frequently asked questions
- Is it compatible with Holosun 507C optics?
- Yes, the RM1C's slide uses the Trijicon RMR footprint, which accepts Holosun 507C, 508T, and 509T models without adapter plates. Mounting requires four #6-32 screws measuring 0.75 inches in length—pistol ships without optics hardware to avoid import restrictions.
- Does it fit Glock 19 holsters?
- Most kydex holsters molded for Gen 3-5 Glock 19s will accommodate the RM1C, though the 4-inch barrel may protrude slightly. I recommend verifying fit with Tier 1 Concealed or Vedder Holsters—both offer RM1C-specific molds if standard G19 retention is too loose.
- How long does shipping take to Montana?
- FFL shipments from Ironclad Armory typically reach Bozeman in 3 business days via FedEx 2Day. Compliance verification adds 24-48 hours before shipment—complete your FFL's paperwork beforehand to avoid delays.
- Can I return it if the grip texture is too aggressive?
- Firearms sales are final once transferred, but Ironclad offers Talon Grips Pro texture overlays for $19.99 that moderate the factory stippling. These adhesive panels install in under 5 minutes and preserve the underlying frame if removed.
- Does this work with suppressor-height sights?
- The RM1C's dovetail accepts standard .330" tall sights, but the factory HiViz front sight clears most micro red dots. For suppressed use, Dawson Precision offers co-witness sets at .394" height—installation requires a sight pusher and 15 minutes of careful adjustment.
