I bought two Bond Arms Derringers last year as their quality and superior craftsmanship make the Derringers they make  better than any other Derringer made in the past or today.  Materials are high grade and being able to switch out barrels with different calibers is fantastic.   You just cannot go wrong with these guns.  And if you need help they actually answer the phone and treat you as a valued customer and NOT a bother.     With different accessories available you can customize the firearm to your needs.
