The Snake Slayer IV from Bond Arms is a two-shot stainless derringer whose 4.25-inch barrel is interchangeable and chambered for .410 bore and .45 Colt. Extended wood grips give a fuller hold than standard derringer stocks. The single-action lockwork uses a hammer that rebounds, firing pins that retract, an extractor that works automatically on opening and a cammed, spring-loaded locking lever. It weighs 24 ounces and measures 7.5 inches overall.

The longer barrel is what defines the IV: compared with the shorter Snake Slayer it tightens .410 patterns and raises velocity, which makes it a better fit for a hiker or rancher who wants a shotshell option against snakes and a .45 Colt option for everything else. The interchangeable barrel system means other Bond Arms barrels fit the same frame, so one gun can swap chamberings. The extended wood grips matter when firing .45 Colt from a 24-ounce gun, and the automatic extractor speeds reloads of the two chambers.
