Ex-Machina:
Back in January, I sent a Blackhawk to David Clements to have something similar made. It will be a 5 1/2 inch octagonal barrel, with a bisley grip frame and hammer. I trust his judgement better about what sort of front sight, so I left that up to him.
But I think you've gotten some good advice about custom revolvers here, make sure it's what you want, like the 5 inch barrel. I've seen Double action revolvers with 5 inch barrels, it's a nice size for good
proportions on a gun.
What sort of grips will you have, or did I miss that part?
