New here/Bond Arms Derringers

I had one once I think it was the Texas Defender 45/410. I had two specialty loads for it. One was what I called a tent load and was intended for use against bears if one got on you while you were in a tent or sleeping bag where it would be about impossible to maneuver a larger gun. This load was put up in 454 Casull cases and loaded with our 400gn hammer head bullet. The load would bloody your thumb with every shot but that is still better than having your skull crushed in a brown bears jaws.
The other load was for the same purpose but was loaded with three 45 caliber round balls put up in 460 S&W cases. The three ball load was a dual purpose load also intended for close range B G repellent.
That Bond Arms is one stout little derringer.

I almost forgot to mention something else I learned about the Bond Arms derringer. On the model I had the Texas Defender there was no trigger guard. The very short throw solid trigger was set very close to the wide beefy frame and was difficult to pull in the conventional manner with the strong grip hand. The reason was that in such a conventional hold while pressing the trigger with the index finger of the grip hand you were also pressing against the frame which required a lot of finger pressure to get the gun to fire. This made it very hard to hold an aim with the gun.
What I learned to do to get the gun to shoot more accurately was to hold the gun as I normally would for a right hand shooter but not use the index finger of my right hand to press the trigger. In the normal fashion the trigger finger would be horizontal across the trigger which is what caused the trigger control problem because with the normal trigger finger in the horizontal position it was also pressing on the frame on each side of the trigger.
With  the normal right hand hold I would lay the right index finger along side the barrel and with the left hand in the two hand grip I would use the index finger of the left hand held in a vertical position parallel with the trigger and press the trigger with the tip of the left index finger. This helped eliminate the finger pressing against the frame and made trigger control much easier.
Once I figured out how to get a smooth lighter trigger squeeze I learned that for shots to about 50 feet the little derringer could be fired fairly accurately and then could be used to take small game out to about 50 feet. For this I liked the Lyman 452460 a 200gn SWC type bullet normally used in the 45 acp. The 452460 at about 700 fps in 45 Colt cases was surprisingly accurate from the little derringer and made it more of a dual purpose gun.
I really liked the Bond Arms derringer but ended up trading it off toward a pick up truck I needed when the old one gave out. Well it didn't really give out but it was burning a lot of oil and not really worth rebuilding. I traded into a Dodge Dakota which I still have and like.
