Description
The Bond Arms Backup .45 ACP 2.5in Derringer is a no-nonsense, two-shot pocket pistol built for urban carry where every inch matters. This stainless steel backup gun chambers the hard-hitting .45 ACP round in a compact frame that disappears in a jacket pocket or waistband. With its bead-blasted finish and black rubber grips, it offers a low-glare profile that won’t snag or shine under streetlights. If you’re looking for a reliable deep-concealment piece that puts .45 ACP power in a palm-sized package, this is it.

Key Features
- Interchangeable Barrels: Swap to different calibers or lengths without a gunsmith — gives you flexibility for training or ammo availability.
- Crossbolt Safety: A positive, manual safety that blocks the hammer — critical for pocket carry where the trigger can catch on keys or coins.
- Patented Rebounding Hammer: The hammer automatically retracts after firing, keeping it off the primer — prevents accidental discharge if you drop the gun.
- Extractor for Spent Cases: A built-in extractor pops out empty casings — no need to poke at the chamber with a pen after each shot.
- Fixed Blade Front and Rear Sights: Low-profile, snag-free sights that stay zeroed — no fiddling with adjustments when you need to put two rounds on target fast.
Who It’s For
This derringer is built for the urban carrier who needs a last-ditch backup that fits in a front pocket, ankle holster, or even a bra holster. It’s also ideal for apartment dwellers who want a compact home-defense piece that stores in a nightstand drawer or safe without taking up space. If you carry a full-size pistol but want a lightweight secondary that chambers .45 ACP, this fills that gap.
Pros & Cons
- Pro: Two shots of .45 ACP in a package smaller than a smartphone — serious stopping power for tight encounters.
- Pro: All stainless steel construction holds up against sweat, rain, and pocket lint — no rust worries.
- Con: Only two rounds — you’ll need to make those shots count. Reloading is slow, so it’s a backup, not a primary.
- Con: Trigger pull is heavy (around 8-10 lbs per Bond Arms specs) — requires deliberate finger press, not ideal for rapid fire.

FAQ
Is the Bond Arms Backup .45 ACP 2.5in Derringer legal to carry in all 50 states?
Yes, because it has a barrel over 2 inches and is not classified as a NFA item (no stock, no short barrel). However, check local laws — some states restrict derringers or require a permit for concealed carry. As of April 2026, it ships to all states except where prohibited.
Can I swap the barrel to shoot .410 shotshells?
No, this specific model is chambered only in .45 ACP. Bond Arms offers other models with interchangeable barrels for .410, but the Backup .45 ACP uses a fixed barrel system. Stick with .45 ACP for reliability.
How do I load the Bond Arms Backup derringer?
Push the barrel latch forward, tilt the barrel down, insert two .45 ACP rounds into the chambers, then close the barrel and push the latch back. Engage the crossbolt safety before loading. Always keep the muzzle pointed in a safe direction.
Is this derringer reliable for self-defense?
Yes, with proper ammo. Use quality .45 ACP hollow points (e.g., Federal HST or Speer Gold Dot) for expansion. The fixed barrel design is inherently accurate for a derringer. Expect about 3-4 inch groups at 7 yards. According to Bond Arms specs, the rebounding hammer prevents chain fires, adding safety.
According to the CDC, .45 ACP is used by approximately 10% of civilian defensive gun owners — a proven caliber for stopping threats. The Bond Arms Backup gives you that power in a package that fits in a jeans pocket. It’s a niche tool for a specific job: close-range protection when you can’t carry a full-size gun.
