The fit is really nice and the sight was packaged very well with screw in marked boxes. I had to go to Osight's website to see which screws i needed but that was easy. When looking at it from behind it looks like there's a big overhang but it barely noticeable from the side. Optic housing is 9.82mm and the slide is 9.65mm, so negligible overhang. Fits the Rounded by Concealment Express holster is have perfectly. Button have to be deliberately pressed on the sight as well. PSA, If you install an optic on an MC9, put loctite on the set screw for rear sight as well. Mine was loose from the factory. Attached File Attached File Attached File Attached File |
