depending on what parts you kneed a good gunsmith can make the parts you need.
I need a safety pin for an FMJ 410 Single Barrel Derringer
To contact FMJ makers of the 45/410 Derringer write to Leinad Inc.... PO Box 579 ....... Ducktown,TN 37326
This weapon was manufactured by the maker of the MAC10. I have an over-under derringer by FMJ Ducktown, TN. It is a 22cal under and a 410/colt 45 over. Some infomantion is under LEINAD which is Daniel spelled backward. Also COBRAY. JD

Check the butt and receiver.
$130.00 New in box.
Yes, it is a 410/45LC combo derringer, and runs about $80-$100.
It should be marked on the gun- something like .410/ 45 Colt.

Yes, one gun manufacturer at least built a two barrel derringer that was chambered for 410 rounds. While a 410 is relatively small, technically is is still a shotgun, and in a pistol as small as the derringer, firing it is a wrist-breaker.
I have seen the 45 version
$100. If you find someone that REALLY wants one maybe a little more.
