Night sights are not good for target/drill practice or competition. They have a small advantage in low light, but not no light, because you still need a weapon mounted light that will black out nights sights anyway. I would go back to black or black, or a fiber optic front. Take a look at Dawson Precision, Taran Tactical and Heines. There are others, but these are then ones I am familiar with. Your other option is to go with a slide mounted dot, which puts the focus only on the target. It's super easy to see, but it takes some serious draw practice to get on it fast. Instead of drawing to the target, like iron sights, you have to bring it straight up in front of you to pickup the dot, then push out. Inside about 7 yards you just look thru the window. These are the various setups I have used over the last 23 years of Glocks.
Left to right: Heine rear, Dawson front, standard Trijicon night sights (carry),
Heine Straight 8 night sights, actually blacked them out after I got them as match product, and Dawson Sevigny fiber optic with ear cut rears.
All my competition guns are now black on black with wide cut rears (.180") with the exception of a G17L upper I just got with a fiber optic front, don't use it much so might leave it alone.
Trijicon 7 MOA red dot, no longer made, similar to the Docter red dot.
Wide cut Heine rear, same as the first gun on the left (original width rear .125")
