Why This Old West Firearms Derringer Stands Out
Having handled hundreds of derringers over the years, 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, functional tool with a specific purpose. The choice of 9mm Luger is the real story here. You get the manageable recoil and widespread availability of 9mm ammo in a format that’s incredibly easy to conceal. I’ve helped many new shooters and families in San Antonio who want a simple, no-frills backup or deep-concealment option, and this derringer often fits the bill. It reminds me of the single-action revolvers I teach with—simple mechanics, clear operation, and a focus on fundamental safety.

How It Stacks Up: Derringer Comparison
| Feature | Old West Firearms Short Bore 9mm | Budget Import Derringer (~$65) | Premium Brand Derringer (~$250+) |
|---|---|---|---|
| Material | Steel frame & barrel | Zinc alloy / pot metal | Stainless or tool steel |
| Quality | Reliable commercial grade | Questionable durability | High-polish, tight tolerances |
| Compatibility | Standard 9mm Luger | Often .22 LR or .25 ACP | Interchangeable barrels (multiple calibers) |
| Shipping | Same-day from TX | Long int’l lead times | Varies by retailer |

This comparison shows the Old West model sits in a practical middle ground. You’re not getting a fragile zinc alloy gun, but you’re also not paying for premium features like interchangeable barrels that a casual user may never need. For a tool that might sit in a pocket or a vehicle console, this balance makes sense.
Pros and Cons From My Bench
What I like:
- ✅ Practical Caliber: 9mm Luger is affordable, available, and effective.
- ✅ Simple Operation: Break-open action is intuitive and safe for beginners to understand.
- ✅ Extreme Concealability: Its profile disappears in a pocket or ankle holster.
- ✅ Nostalgic Design: It has the classic derringer look and feel.
- ✅ Solid Value: At this price point for a steel 9mm, it’s hard to beat.
Points to consider:
- ❌ Limited Capacity: Two rounds is all you get. This is a last-resort tool, not a primary firearm. If you need more rounds, see our semi-automatic pistols.
- ❌ Heavy Double-Action Trigger: The trigger pull is long and heavy, which is typical for safety but requires practice. It’s not a target pistol.
- ❌ Basic Sights: Sights are minimal, suited for close-range point shooting.
Who This Derringer Is For (And Who Should Look Elsewhere)
Buy it if:
- You want a dedicated, ultra-concealable backup gun (BUG).
- You’re a history enthusiast who appreciates the derringer format with a modern caliber.
- You need a simple, no-safety-to-fumble firearm for very close distances.
- You’re looking for an affordable introduction to the derringer style.
Skip it if:
- You need a primary defensive firearm with higher capacity. (Consider a compact 9mm instead).
- You plan on high-volume range practice. The derringer action isn’t meant for that.
- You require adjustable target sights or a light trigger pull.
- You’re looking for a multi-caliber system. This is a dedicated 9mm platform.
Handling Common Concerns
“Is a two-shot gun even useful?”
It’s a valid question. In my view, a derringer like this serves a specific niche: a deep-concealment option when carrying anything larger isn’t possible, or as a final backup. It’s not meant to replace your everyday carry. I often tell students, “Two rounds of 9mm you have is better than ten rounds you left at home because the gun was too bulky.”
“How’s the recoil?”
With full-power 9mm, you’ll feel it. The small, lightweight frame transfers energy. It’s manageable, but it’s not a soft-shooting range toy. I recommend starting with lighter 9mm target loads to get accustomed to it. The grip design helps control the snap.
“Is it reliable?”
The simplicity is its virtue. There’s no magazine to fail, no slide to cycle. It’s a firing pin hitting a primer. Keep it clean, and it should go bang when you pull the trigger. I’ve seen these hold up well when used for their intended purpose.
Frequently Asked Questions
What type of ammunition does this derringer use?
This derringer is chambered specifically for 9mm Luger, also known as 9×19 Parabellum. It is designed for standard pressure 9mm ammunition. I do not recommend using +P or +P+ loads, as they generate excessive pressure for this lightweight frame.
How do you load and unload the Old West Firearms derringer?
To load, push the barrel release lever (usually on the left side) and tip the barrels downward. Insert one round into each of the two chambers. Close the action firmly until it clicks. To unload, open the action and tip the muzzle up to let the rounds fall out, or manually extract them. Always visually and physically confirm the chambers are empty.
Is this derringer suitable for a beginner?
It can be, with proper supervision. The manual of arms is very simple, which is good. However, the heavy trigger pull and significant recoil require dedicated practice to master safely. I always recommend professional training for any new shooter, regardless of the firearm.
What kind of holster works with this gun?
Due to its small size, it fits most generic derringer or small pistol holsters. Look for pocket holsters, ankle holsters, or vertical belt holsters designed for derringers. A good holster that completely covers the trigger guard is essential for safe carry.
How accurate is a short-barrel derringer?
Realistic expectations are key. This is a close-range firearm. The short barrel and basic sights make precision shooting at distances beyond 7-10 yards very challenging. It’s designed for point-and-shoot scenarios at arm’s length.
