Whats the point?
If you want a revolver buy one!
If you want a 410 Buy one!
Why create such a monstrosity?
For the money that cost Ill take a Ruger in .45 Colt + a single shot 410.($500)
Shot out of the rifled barrel will make it useless anyways at any range.
And if I wanted a rifle in .45 Colt it would be a lever!!!!!!
