Key Features
- Integrated compensator — Why it matters: Reduces muzzle rise by up to 30% in real-world testing, so you land faster follow-up shots without fighting the gun.
- Optic-ready slide with Viridian RFX11 — Why it matters: You get a 3 MOA green dot out of the box, no plates to buy, no gunsmith visit needed.
- 3.6-inch crowned match barrel — Why it matters: Hammer-forged rifling delivers consistent accuracy at self-defense distances, and the crown protects the bore during holster wear.
- Subcompact grip with full-size controls — Why it matters: Ambidextrous slide stop and reversible magazine release let you run the gun strong hand or support hand without retraining.
- Striker-fired trigger with 5.5-lb pull — Why it matters: Clean break and short reset reduce the chance of pulling shots under stress, critical in a hallway or parking lot.
Who It’s For
This bundle is for the urban CCW holder who carries daily in an apartment or city environment. If you need a gun that conceals under a T-shirt, shoots flat with a compensator, and already has a quality optic mounted, the RM1S Comp fits that lane.
Pros / Cons
- Pro: Comes with a Viridian RFX11 green dot, saving you $150+ over buying separate.
- Pro: Integrated compensator works with standard 9mm loads, no need for +P ammo to feel the benefit.
- Con: Aftermarket holster support is still growing — you may need to try a few brands before finding your perfect carry rig.
Comparison
| Feature | Rost Martin RM1S Comp | Zev Technologies OZ9C | Lone Wolf Distributors Timberwolf |
|---|---|---|---|
| Barrel length | 3.6″ with comp | 4.0″ | 3.9″ |
| Optic included | Viridian RFX11 green dot | None | None |
| Compensator | Integrated | Optional add-on | None |
| Price | $519.71 | $1,200+ | $450 (base) |
| Weight (unloaded) | 19.5 oz | 24 oz | 22 oz |
The RM1S Comp undercuts the OZ9C by over $600 and still includes a dot and comp. The Timberwolf is cheaper but lacks both features, so you’d spend extra to match this bundle.
FAQ
Does the Rost Martin RM1S Comp come with a holster?
No, it ships with the pistol, one 10-round magazine, cable lock, manual, and the Viridian RFX11 optic. You’ll need to source a holster separately.
Is the compensator removable?
Yes, the comp is threaded onto the barrel and can be removed with a standard wrench if you prefer to run the gun without it.
What footprint does the optic use?
The slide is cut for the RMR footprint, and the included Viridian RFX11 uses that same pattern. It also fits Holosun 407C/507C and Trijicon RMR.
Can I use +P ammunition in this pistol?
Yes, the RM1S Comp is rated for +P 9mm loads per Rost Martin specs. The compensator handles the extra pressure without issue.
