Did you buy the #4 set for the standard CZ 75 ? If so you should have gotten the #5 set.
Yes, they're the cz75 sights. However, if I had gotten the #5 set my POI would be even higher.
All of the standard cz75 Meprolight night sights use a 6mm #5 front sight. The elevation is adjusted by using different height rear sights. A short rear sight will bring your POI down, a taller rear sight will make it go up. I bought the set with the shortest rear sight offered at the cz store because I knew my P07 would be a bit high, considering it had a #1 front sight from the factory.
To Process:
You have the #5 Meps, they might work just fine for your P07 but they won't for mine. You do have an advantage though, you haven't installed them yet so you might be able to return them if you want.
