Jaque, don't worry about it. It is set up just right. I never used those holes because I put a G-23 in mine and had to modify the fire wall just slightly. If you are using the mount supplied for the .90 or 1.20, it will do nicely. Good luck and enjoy a fine model.

P.S. Be sure and use red locktite on the mount screws. It really secures them better than the blue.
