I bought my Bond Arms mini 45 because it used the same caliber ammo as my SAA Big Bore Bounty Hunter and my Henry Arms Mare's Leg. Once I shot this gun I knew I had made a GREAT decision. Since receiving my Mini 45 I have had my decision confirmed by multiple people. My son, former Marine, was totally against derringers because of previous encounters. Today, he shot the Bond Arms derringer and he was sold on them. He now wants one for himself. I love my Mini 45!
