Well, that's something new. Weird sword/gun combo.

I've seen sword guns before, but this is a whole new way of doing it. So odd!

Justin,
Looks like you have a new random idea to build. Would be great as a flintlick rather than a percussion action.

An advantage with a flintlock would be the loss of the percussion drum on the hilt/barrel portion.

I do like the brass ring making the "cannon-type" muzzle on the pistol.  Lots of details to sort through, Justin.
