Description
The 4.25-inch barrel is Bond Arms' longest offering for their derringer lineup, and this .45 ACP version delivers extra sight radius and velocity compared to shorter configurations. Known as the Snake Slayer IV style, it comes in a polished satin stainless finish that resists corrosion and keeps a professional working-gun appearance.
One of the biggest advantages of owning a Bond Arms derringer is the ability to transform your gun in seconds. This barrel swaps onto any original Hand Cannon frame using just the included Allen wrench. No special tools, no gunsmithing required. Remove the hinge pin, install the new barrel, and you're ready to go. It's the kind of versatility that keeps a single frame relevant across different shooting situations and preferences.
Why the 4.25" Length Matters
The extra length provides tighter shot patterns, higher velocities, and more consistent accuracy compared to the 3-inch and 3.5-inch alternatives. Longer sight radius naturally improves your ability to aim precisely at close range, where derringers do their best work. It also gives your hand something more substantial to work with when managing the derringer's notable recoil.
Important Note on the .45 ACP Barrel
This rimless cartridge barrel does not include an extractor. After firing, you'll eject spent cases manually. That's not a drawback unique to Bond Arms—it's simply how centerfire pistol and rimless cartridges work in their derringer platform. Rimmed cartridges like .45 Colt and .357 Mag feature automatic extractors for faster reloading.

Frequently Asked Questions
Will this 4.25 inch barrel fit my Bond Arms derringer?
Yes, if you own an original Bond Arms Hand Cannon derringer. This barrel will not work with Stinger, Stinger RS, or Cyclops frames. All original Hand Cannon frames accept this barrel and all other interchangeable Bond Arms barrels.
Why doesn't the .45 ACP barrel have an extractor?
Extractors are only needed for rimmed cartridges. Since .45 ACP is a rimless cartridge, there's no rim for the extractor to grab. You'll manually eject spent cases, which is standard practice with rimless ammunition across all firearms.
How hard is it to swap this barrel for a different one?
It takes about a minute. Remove the hinge pin with the included Allen wrench, pull off the old barrel, slide the new one on, and reinstall the pin. No special knowledge or tools required beyond what comes in the box.
What's the advantage of the 4.25 inch length over shorter barrels?
The longer sight radius improves accuracy at close range, you get higher velocities, and the extra weight helps manage recoil. It's Bond Arms' longest barrel offering, giving you maximum sight radius and performance from your derringer.
