I’m going to be sending off a 43x to Battlewerx to be cut for an EPS carry. If I have the cut in front of the rear dovetail, will the factory plastic sights co-witness at all? Should I put the cut over the rear dovetail and just use the rear sight notch on the EPS carry? Just trying to weigh all the options here.

Had a slide on Glock 22 milled locally it has a CH Precision plate standard height Trijicon irons and EPS Carry. Even with the plate I can see about the top 1/4 of the irons. If you don’t need a plate you would have plenty of the irons showing.
Even if you eliminate the rear sight to bring the dot back I think you would be OK and there would be less chance empty ejecting brass would strike the front glass.

Note: on a pistol you are familiar with even if you broke the sights off entirely you should be able to hit a man size target at 15 yds or closer. And he who shoots the mostest the firstest runs the other guy off….

Valid points, thank you sir.

Did you have your G22 milled for RMR and now you’re using a RMRc adapter for the EPS?

With Glock 43X  MOS, EPS Carry, and factory plate, you can see less than half the from sight with the rear drifted out.  I am thinking about putting in a taller front sight and seeing how that works.  I am sure it would effect POI.  As the previous poster said, sights are a reference point.

The sight notch on the EPS carry is pretty small. If you leave the rear dovetail you will still have the option of adding taller backup sights later.

This is a 43X MOS with studs removed and 407k direct attached. The EPS is thinner and should have plenty of cowitness.

Awesome, thank you!

I have a 43X MOS with a RMSc direct mounted. You can see and use the irons. Honestly with a quality optic you should not have to use the irons. Attached File
