Description
The ROST MARTIN RM1F TACT 9MM 24+1 BLK 4.5″ TB is a factory-threaded, full-size 9mm pistol built for shooters who demand suppressor-ready performance right out of the box. With a 24+1 round capacity, black nitride finish, and a 4.5-inch threaded barrel, this handgun delivers high-capacity firepower without the aftermarket wait. Priced at $489.38, it’s a direct competitor to custom shop builds at a fraction of the cost.

Key Features
- 24+1 Round Capacity — Why it matters: Two full boxes of 9mm in one magazine means fewer reloads during training, competition, or home defense. You stay in the fight longer.
- Factory-Threaded 4.5″ Barrel (1/2×28) — Why it matters: No gunsmith visit needed. Threads are cut and protected by a thread cap, so you can mount a suppressor or compensator immediately.
- Black Nitride Finish — Why it matters: Corrosion-resistant and harder than standard bluing. The slide and barrel stay slick even after thousands of rounds in humid conditions.
- Optic-Ready Slide (RMR footprint) — Why it matters: Mount a red dot without milling. Direct-mount design keeps the slide profile low and co-witnesses with standard-height iron sights.
- Aggressive Grip Texture — Why it matters: 360-degree stippling locks the gun in your hand, even with sweaty palms or gloves. No slip, no shift.
Who It’s For
This pistol is built for shooters who want a suppressor-ready, high-capacity 9mm without paying custom shop prices. It’s ideal for competitive shooters in USPSA Limited or Carry Optics, home defenders who want maximum magazine capacity, and range enthusiasts who prefer a threaded barrel for a compensator or can. If you already own a suppressor in 1/2×28, the RM1F TACT is plug-and-play.
Pros & Cons
- Pro: 24+1 capacity beats most factory full-size pistols (Glock 17: 17+1, Sig P320: 17+1).
- Pro: Threaded barrel included at no upcharge — saves $100–$150 vs. buying an aftermarket barrel.
- Pro: Optic-ready slide with RMR footprint reduces upgrade costs.
- Con: Aftermarket holster and magazine support is limited compared to Glock or Sig — expect fewer quick-ship options as of early 2026.
Comparison
| Feature | Rost Martin RM1F TACT | Zev Technologies OZ9 | Lone Wolf Distributors Timberwolf |
|---|---|---|---|
| Capacity | 24+1 | 17+1 | 17+1 |
| Threaded Barrel | Factory (4.5″, 1/2×28) | Optional ($150+ upgrade) | Factory |
| Optic Ready | Yes (RMR) | Yes (RMR) | No (requires milling) |
| Price | $489.38 | $1,200+ | $550–$600 |
| Weight (empty) | 26.5 oz | 28 oz | 25 oz |
The Zev OZ9 is a premium custom build with tighter tolerances, but costs more than double. The Lone Wolf Timberwolf is a solid Glock clone, but lacks factory optic cut and has lower capacity. The RM1F TACT gives you more rounds, a threaded barrel, and an optic-ready slide at a price that undercuts both.
FAQ
Does the RM1F TACT come with a thread protector?
Yes. The factory threaded barrel ships with a black steel thread protector installed. It’s 1/2×28 pitch, standard for most 9mm suppressors and compensators.
Will this fit a Safariland or other duty holster?
Most full-size 9mm holsters with an open muzzle (e.g., Safariland 6360 for Glock 17 with TLR-1) will fit, but confirm your light model. The threaded barrel requires a holster with an open bottom or a threaded barrel channel. As of April 2026, dedicated Rost Martin holsters are limited; consider custom kydex options from companies like Red Hill Tactical.
Can I use standard Glock 17 magazines in this pistol?
No. The RM1F TACT uses proprietary Rost Martin magazines. They are not cross-compatible with Glock, Sig, or other brands. Extra magazines are available directly from Rost Martin and select distributors.
Is the trigger adjustable or upgradeable?
The stock trigger is a flat-face, single-action with a 5.5–6 lb pull (per manufacturer specs). It is not user-adjustable, but aftermarket triggers from Timney or Apex are expected to be released in 2026. The trigger shoe uses a standard Glock-style trigger bar, so some drop-in triggers may fit with minor fitting.
