The Bond Arms BABL35035738 Derringer 38 Special/357 Mag Satin 3.50" Stainless Steel delivers the recognizable Bond Arms reliability with a satin stainless build and a 3.5 inch barrel that will fit any original Bond Arms hand cannon frames (not Stinger), allowing you to refresh the look or broaden caliber capability for concealed carry. This replacement barrel maintains Bond Arms signature fit and finish, providing clean lines and durable performance for everyday carry or range work, while enabling the versatility of switching between .38 Special and .357 Magnum offerings in a compact, concealable platform.

With its satin stainless steel construction, this barrel delivers corrosion resistance and a smooth aiming profile, pairing seamlessly with Bond Arms frame geometry for reliable cycling and quick, repeatable shots. Ideal for enthusiasts seeking a functional upgrade to their favorite derringer, it blends practical caliber options with a refined finish to support responsible, accurate concealed carry and personal defense applications.
