This is a really neat concept: I would be extremely pleased if only the thing would go off once in a while.
If you only want a display piece, or if you are a frustration addict, I would heartily recommend this firearm: if otherwise, contracting diphtheria might be more fun.
The first problem was it shipped without a trigger. Dixie took care of that by quickly sending one (thank you Dixie!). Polishing, assembly, etc. then went really well, and the piece looks great. The serious problems then presented themselves: when the hammers were cocked, both mainsprings slipped forward out of their slots at the rear of the frame. I did not remove any material here: either the springs are too short or the cutout in the frame is too long. I glued a wedge in as a temporary fix to this, which worked: but it revealed problem #3: the gun would not detonate a cap until the 4th or 5th attempt. And Problem #4 MIGHT not be the gun's fault: the caps would not ignite the powder. Widening the flash channel, using magnum caps, and real black powder instead of Pyrodex might fix this, but at this point, I need to find a way to make the caps go off reliably before the gun is good for anything other than display.
