I've settled on the 0.180" high front Ameriglo Orange/Tritium and a blacked out standard height rear for both my Glock 19.5 (USPSA, Training) and 43X (Carry). It hits center of dot hold out to 25 yards for me with both AE115 and HST147.
They have a 0.165, which might be more along the lines of a top of the front sight post hold; but it being my (very limited) experience with Glocks what works for me might not work for everybody.
I'll find a link and edit this post to include, one sec.
