OK, after a long time away from the Unique, I've gotten an urge to work on it again.
To my thinking the primary cause of the inaccuracy is that the barrel is quite loose in the frame/slide.
There is a .003 gap between the slide and barrel, allowing the end of the barrel to move slightly less that 1/8".
The basic challenge is to make the barrel & slide fit closer. When the pistol is in battery, the barrel slides over a wide spot in the barrel. The barrel is not permanently affixed to the frame, just held in place with the recoil lugs.
I'm on the fence about how to cure this issue. My initial take on it is to enlarge the slide and install a bushing. However, the hole is an odd shape - It's almost an oval, except the lower side of the hole is a different radius, and has sharp corners. I can only imagine it was broached at the factory.
My alternate thought would be to solder or braze a pad onto the barrel.
Any thoughts or suggestions would be appreciated.
