Sorry, but I don't own one.
Having said that, I do have an opinion though.
I am looking at the Dixie 2003 catalog and they say they think it is worth $425 Finished or $160 for the kit. I note that the kit does not include casehardening, engraving or checkering.
To me, the prices are a bit high. :imo:
Whether it is worth that much to you, only you can decide but I will say if you are buying it to shoot it, remember this Derringer was designed as a personal protection gun for ranges from 1 to 8 feet.
IMO if Lincoln would have been 6 feet from Booth, the worst he would have had was some powder burns on the back of his neck. ::
