The Bond Arms Backup is designed for easy concealment but packs the same protective power as a full-sized handgun. The Backup pairs a textured rubber grip frame with a bead-blasted, anti-glare double-barrel that's made from durable stainless steel. With an automatic spent casing extractor; retracting ring pins; a cross-bolt safety; a spring-loaded, cammed locking lever; and Bond's patented rebounding hammer, the Backup is safe and easy to use for shooters of all experience levels. If a different barrel length or caliber suits your fancy in the future, the Backup is compatible with all of Bond Arms' interchangeable barrels. Fixed sights. 4.5" total length.
