Have you considered what you will do about a repair on such a gun, should one be needed? There will be zero chance of finding a replacement part. It will have to be made by a very talented 'smith, and it will be very expensive.

Not trying to dissuade you from the purchase, just mentioning possible future events. I'm an optimist, so I'd probably buy it too if I wanted it. But, reality should not be denied.

May God bless America and those who defend her.
