Stick with 3-dot night sights... which is how most who use Glocks for work will do.
Anything you have to look or peep through just makes you slower - including glass/red dots.
I like tritium dots but for speed there is no substitute for learning to point shoot and make sight acquisition secondary
Took me years and tens of thousands of rounds to get good at it but once you do it’s nearly like riding a bike
It’s not seriously high precision but I can generally draw and be in target firing before most people have found their front sight
Again, lots of practice but even an air pistol or 22 will get you a long ways along the process
Very short distance. I can hit those 100% with any decent sights.
