Bond Arms derringers have a loyal following for their solid stainless build, and the Big Bore models chambered in heavy rifle cartridges like .45-70 push that reputation into novelty territory. Owners describe recoil in the big-bore chamberings as sharp given how little gun there is to absorb it, and most treat this as a gun to shoot sparingly rather than run through a range session.

The patriotic Commander in Chief engraving is exactly the kind of feature that splits opinion. Political-theme collectors seek it out specifically for the limited-edition artwork, while shooters who just want a Bond Arms Big Bore in .45-70 sometimes prefer the plainer standard finish. Either way, owners generally agree the engraving work itself is done cleanly on the stainless frame.

As a practical carry piece, most buyers treat the .45-70 Big Bore as a collector or novelty item rather than an everyday defensive gun, since a two-shot break-action derringer in a rifle cartridge is a niche tool. The rebounding hammer and cross-bolt safety get credited as sensible carry safety features on an otherwise unconventional handgun.
