Default CZ 75 SPO1 Adjustable rear sight.

Hi I have bought an LPA adjustable rear sight for my CZ 75 SPO1. My question is after receiving the sight I have noticed there is no retaining screw for holding the sight in place. I am wondering what holds it in place is it an interference fit does it need glued in place. ? Any advice would be appreciated.

Yes, the fit of the dovetail is an interference (press) fit into the slide. Normally new sights are just a bit over sized in order to allow filing down the dovetail on the sight to obtain a tight fit into the dovetail in the slide.

If you happen to have one that is slightly loose, you can secure it with a high strength loc-tite thread locking compound.

When I decided to add a similar sight to my CZ75BD, I figured that rather than me beating on it haphazardly with a hammer & punch, it was better for all concerned to pay the money and have a gunsmith do it correctly. Mine was tight enough that unwanted movement isn't a worry.

Yes, they are press fit. You take a fine file or coarse stone and remove a little metal at a time from the sight until it starts into the dovetail. Go slow and try fitting often. If you happen to take too much metal off, you can use a punch and place a dimple in the slide dovetail to tighten the fit.

If you decide to use a hammer and punch, remember that masking tape is your friend.
