I just sniffed around in the man room, I found another set of 1911 grips. These are double diamond rosewood, non-ambi. But, these are slim grips...not standard thickness. So you'll need slim bushings and screws to go with 'em, which I don't have.
Also got the Beretta 92 service pack from Wolff, still unopened. If memory serves, it contains every spring for the whole gun.
