That is some strong steel that they use. It will eat up some basic milling equipment tooling. Great hand gun to have if you need to pistol whip someone.
What did you get it for, if you don't mind me asking? That's a great project gun you got right there...
What are you thinking? I am thinking a .460 Rowland would be a great addition - and you won't experience the problems Cane had with his Colt.
