I suggest against night sights!
At any distance at which you feel truly confident shooting at night, glow-in-the-dark sights will serve you no better than will ordinary, black (invisible at night) sights.
If you can see your night sights, you can't see your target as well as you should. The sight glow interferes with seeing a target in the dark. Further, if it's so dark that you can't see your target, you shouldn't shoot.
After the appropriate practice time, your "muscle memory" should allow you to place quite accurate hits on a target that's seven yards away without using your sights at all. In the dark, shooting at distances past seven yards is more a "crap shoot" than it is an exercise in marksmanship.
No gadget, including night sights, will remove from you the necessity of putting in lots of dry-fire and shooting practice. If you practice as you should, and as much as you should, you will find that you don't need glow-in-the-dark sights.
