The Bond Arms Backup 9mm derringer is a compact, single-action pocket pistol built for deep concealment and last-resort defense. At just 4.5 inches long and 18 ounces, this two-shot 9mm fits easily in a pocket, ankle holster, or backup carry rig—exactly the kind of lightweight, no-fuss insurance piece that appeals to shooters who prioritize accessibility over capacity. The stainless steel frame wears a durable black crinkle powder coat that resists corrosion while keeping a low profile.
What sets the Backup apart is its practical engineering. A spring-loaded cammed locking lever creates a rock-solid barrel-to-frame fit and makes loading and unloading dead simple—no wrestling with loose parts. The rebounding hammer and retracting firing pins are safety features you want in a pocket gun, while the crossbolt safety keeps the trigger secure until you're ready. Rubber grips offer a sure hold even if your hands are wet or gloved, and fixed sights cut out unnecessary complexity.
Bond Arms designed the Backup around interchangeable barrels, so you're not locked into 9mm forever; if your needs or preferences change, barrel swaps are straightforward. The 2.5-inch barrel balances concealability with velocity, a proven formula for compact defensive handguns. This is purpose-built gear for serious carry—no mall ninja aesthetics, just a tough little pistol that does one job and does it well.

Frequently Asked Questions
What makes the Bond Arms Backup suitable for pocket carry?
At 4.5 inches overall and just 18 ounces, the Backup is genuinely pocketable—lightweight enough not to drag your pants down and small enough to disappear into a jacket pocket or deep carry holster. The fixed sights don't snag, and the profile is as snag-free as a purpose-built pocket pistol gets.
Can I use a different caliber barrel on this gun?
Yes. Bond Arms designed the Backup with interchangeable barrels, so you can swap calibers without buying a second gun. Check Bond Arms' barrel compatibility chart to confirm which barrels fit your model.
Is the Backup safe for everyday carry?
The Backup includes multiple safety features—a crossbolt safety, rebounding hammer, and retracting firing pins—all standard for modern derringers. These passive and active mechanisms keep the gun secure in the holster and during handling. As with any firearm, proper holster selection and safe storage practices matter.
