I called Ameriglo with this same question and according them, the Gen5 slides have a different pitch/angle to them, so if you put a GL-201 on a gen5 it will consistently shoot higher than you are aiming. the GL-5201 is a different height than the GL-201 but it is not "suppressor height".
Yes, the AmeriGlo I-Dot Night Sight Set is compatible with all Gen 5 non-MOS Glock pistols.
These AmeriGlo I-Dot Night Sight Sets will fit a Gen 5 Glock 19.
The AmeriGlo I-Dot Night Sight Set will not work for a Glock 43X. You will need the model at the link below.

That is correct. Walther did design the PDP to take Glock sights.
Yes, this will fit the Glock 45.
No, it may change your holds for different distances, but it will fit and work with your firearm.
It will, but the heights will change your point of aim/point of impact as these are Gen 5 height. Gen 1-4 sights are a different height.
Yes, it will.
GL-5201 is intended for Gen5 17, 19, 26. It should fit the 45 as well, you may wish to confirm with Ameriglo at 470-223-4163 before ordering.
