I got the idea from Doc Holladay here on the sight, but I had a Skinner ghost put on a CZ sxs. The rear sight was too high for the factory bead and it shot high. I talked to the guys at Skinner and sent the barrels to them. I explained how I wanted it to shoot out to 40. They knew about how high to mill an express-type front sight base with a brass bead on it. It's perfect now. I think if you put the ghost rear on, you'll just have to try it. You might get lucky and a pipe front sight will be the proper height. Skinner provided great service and the cost was reasonable.
