2. Design: The Defender features a two-shot design with two independent barrels, one for each shot. It has a break-action, which allows you to load and unload the firearm by pivoting the barrels down.
3. Construction: Typically, the Bond Arms Defender is built with stainless steel for durability and corrosion resistance. The handle is often made from wood or rubber for a better grip.
