The Snake Slayer IV has a 4-1/4” long barrel rather than the 3-1/2" barrel found on the original. This longer barreled Snake Slayer provides tighter shot patterns, higher velocities, and even more manageable recoil than the standard Snake Slayer. The grip has been extended as well for added comfort. Bond Arms' patented rebounding hammer is quick-acting and dependable. The frame is solid stainless steel for durability. Spring-loaded, cammed locking lever. Spent casting extractor rod. Retracting Ring pins. Cross-bolt safety.
