Why This Old West Firearms Short Bore 9mm Derringer Stands Out
After handling hundreds of derringers in my career, from antique Remingtons to modern Bond Arms pieces, I see the appeal of this specific model. It’s not trying to be a high-end competition piece. It’s a straightforward, no-frills backup or deep-concealment option. The big win here is the 9mm Luger chambering. You’re getting a cartridge with proven stopping power and wide availability, housed in a package that’s about as small as they come. For families I coach, having a secondary firearm that shares ammo with a primary 9mm pistol simplifies logistics and training. You’re not stocking a separate, obscure caliber just for your backup gun.
I’ve built custom 1911s that cost more than my first car, but there’s a raw, honest utility to a simple derringer. This one reminds me of the guns I used to see as an armorer—tools meant for a specific, close-range job. The single-action trigger is a safety feature in itself, requiring a deliberate pull for each shot. It forces the shooter to be intentional, which is a good habit for any skill level.
Detailed Specifications
Let’s break down exactly what you’re getting. These specs are based on my inspection of the unit we have in stock and manufacturer data.

How It Stacks Up: Derringer Comparison
To give you real context, let’s put this Old West model against two common alternatives you’ll find on the market. I’ve handled all three tiers.
| Feature | Old West Firearms Short Bore 9mm | Generic Import .38 Derringer (~$65) | Bond Arms Snake Slayer .45LC/.410 (~$350+) |
|---|---|---|---|
| Material | Alloy Steel | Zinc Alloy (Pot Metal) | Stainless Steel |
| Quality | Functional, Heat-Treated | Questionable Longevity | Premium Fit & Finish |
| Compatibility | 9mm Luger (Common) | .38 Special (Common) | .45LC/.410 (Versatile) |
| Shipping | Same-Day from TX | Varies, Often Slow | Varies by Dealer |
| Lifespan/Durability | Good for Intended Use | Limited, Not for Frequent Fire | Heavy-Duty, Long Lifespan |
| Price | $120.99 | $60 – $80 | $350 – $500 |
The takeaway? You’re in a solid middle ground. You’re avoiding the questionable metallurgy of the cheapest imports, but you’re not paying for the over-engineered robustness of a Bond Arms—which, frankly, is more gun than most people need for a derringer’s role.
What You’ll Like (And What You Should Know)
Based on my time with this firearm, here’s the honest breakdown.
Pros:
- ✅ Practical Caliber: 9mm Luger is affordable, effective, and likely matches your other firearms.
- ✅ Extreme Concealability: This thing disappears in a pocket or ankle holster.
- ✅ Simple Operation: Top-break action is intuitive; no complex controls to fumble with.
- ✅ Single-Action Safety: The deliberate trigger pull is a built-in safety for a close-quarters tool.
- ✅ American Made: Manufactured in the USA, which matters for parts and support.
Cons:
- ❌ Limited Capacity: It’s two shots. That’s the derringer trade-off. If you need more, see our semi-automatic pistols for higher-capacity options.
- ❌ Basic Sights: These are minimal fixed grooves. It’s a point-and-shoot tool for very close range.
- ❌ Snappy Recoil: Firing 9mm from a 12-ounce frame has a kick. It’s manageable, but new shooters should be prepared.
Who This Derringer Is For (And Who Should Pass)
Buy it if: You want a dedicated, ultra-concealable backup gun (BUG). You’re a 9mm enthusiast who values caliber commonality. You appreciate the historical design of a derringer but want modern ammunition. You need a deep-concealment option for specific situations.
Skip it if: You need a primary defensive firearm. You’re looking for a high-capacity or easy-to-shoot pistol for new shooters (check our .22 LR trainers instead). You plan on high-volume range sessions—this is a tool, not a plinker.
Common Questions & Concerns
“Is a two-shot gun even practical?” It is, but only for a specific role. As a last-resort backup or for very specific concealed carry needs, two shots of 9mm at contact distance is a formidable option. It’s not your everyday carry unless your threat model is extremely narrow.
“How’s the trigger?” It’s a single-action trigger. It’s fairly heavy and long, by design. This isn’t a target pistol. The pull is consistent and requires a deliberate action, which I consider a safety positive for this type of firearm.
“Can I use +P ammunition?” I do not recommend it. The firearm is designed for standard pressure 9mm Luger rounds. Using +P or +P+ ammunition increases stress and accelerates wear. Stick with standard 115gr or 124gr FMJ for practice and quality JHP for defense.
Frequently Asked Questions
Is the Old West Firearms Short Bore Derringer reliable?
For its intended purpose as a close-range, limited-use firearm, it is reliable with quality ammunition. Like any derringer, keeping it clean and using ammo it likes is key. I’ve found it functions best with round-nose FMJ and standard pressure jacketed hollow points.
How do I load and unload this derringer?
Push the barrel release lever (usually on the left side) and tip the barrel assembly upward. This exposes the two chambers. Insert rounds, then close the barrel until it clicks locked. To unload, open the barrel and tip the muzzle down to let the rounds fall out, or use an extractor tool if they’re stuck.
What kind of holster works with this gun?
You’ll want a pocket holster or a small ankle holster designed for derringers. A holster is non-negotiable for safety—it protects the trigger and keeps the gun oriented correctly. Many universal nylon or leather pocket holsters for small pistols will fit.
Is this a good first gun?
Generally, no. The limited capacity, snappy recoil, and basic sights make it a challenging and niche first firearm. I typically steer beginners toward a full-size or compact 9mm semi-auto or a .22 LR rifle for foundational skills. This is better suited as a secondary option for an experienced shooter.
Can I use it for concealed carry?
Yes, that is its primary design purpose. However, check your local and state laws regarding firearm concealment. Its small size makes it easy to conceal, but ensure you are legally permitted to carry a concealed firearm in your jurisdiction.
