I have used Tru Glo. The main reason to use sights. It forces you to keep your head down.
Stay away from any magnetic mounts. You will loose them. The Tru Glo I used allowed for windage and elevation. They used a hex screw to clamp to the vent rib. Simple to put on or off.
I have also used the Tru Glo that uses a plastic wedge to lock the sight body in place. Those are nice too.
Know the thickness of your vent rib as there are different models.
Used those for years until my old eyes could not adjust.
Now use a scope with a diamond reticle.
