We do not offer tall sights for the factory rear dovetail. If you choose to keep your factopry rear dovetail, you will need to get a set that fits the factory rear dovetail.
This is for a Glock black tall rear iron sight and a CZ P10C black tall front sight.
The first option in the drop down box (.507") is for a new dovetail BEHIND the optic. The second option in the drop down box (.394") is for a new dovetail in FRONT of the optic.
These are all tall sight listings.
