The Bond Arms BABL425 derringer barrel is a 4.25-inch replacement barrel for Bond Arms derringer frames, commonly known as the Snake Slayer IV barrel. If you own a Bond Arms hand cannon and want to refresh its look, extend its sight radius, or swap caliber capability on the fly, this satin stainless steel barrel gives you that flexibility without buying a whole new firearm. It fits any original Bond Arms frame (the Stinger is the exception), so it's a straightforward upgrade path for shooters who've already committed to the Bond Arms platform.
Bond Arms built their reputation on derringers that pack serious stopping power in a compact package, and their modular barrel system lets you get more versatility from a single frame. The 4.25-inch length is the longest barrel currently offered for Bond Arms derringers, giving you a longer sight radius and velocity advantage over shorter barrels—useful whether you're tuning the gun for a particular load, load testing at the range, or simply preferring the sight picture and ergonomics a longer sight radius provides. Finished in satin stainless steel, the barrel resists corrosion and pairs cleanly with most frame finishes.
This barrel is available in .38 Special and .357 Magnum, giving you the option to shoot either cartridge depending on your preference and the ammunition you have on hand. As with all Bond Arms barrels, fit and function are straightforward—it's one of the appealing aspects of the modular design.

The BABL425 is available in either .38 Special or .357 Magnum. You'll need to order the specific caliber for the ammunition you intend to shoot. If you want to shoot both calibers, you would need to purchase separate barrels for each.
The product is the barrel itself. Verify with Bosque Outdoors regarding any additional components, tools, or installation instructions that may be included in your order.
