I put Ameriglo iDot pros on my 19 and really like them. Single dot outlined in orange on the front sight , single dot on centered rear sight. Wasn't looking for night sights, just fast acquisition day sights. They were less the most other sights, do what I want during the day, the night sight is a bonus.
With 60 year old eyes the far sight is sharp, near night blurred. easy to use.
There are so many sight options available, peoples eyes and preferences are different. I spent a year haunting the LGS and everybody at the range trying sights, plus the wisdom og GT. Suggest you do the same to avoid an expensive mistake.
Isosceles? Weaver? I practice shooting over my shoulder while running away!
