I have a glock 23 that I'm about to order some night sights for, and I'm between the trijicon and the ameriglo operator series. I like the trijicon's for the reason they seem to be the most used out there, but on the other hand I like the operator ameriglo's because the rear sights is tritium only, no white ring, and the front sight has a larger tritium dot with white ring than the trijicons. I can get either for $80 +$4 shipping from glockparts.com what's everyone's opinion on these? and is glockparts.com a reputable company to order from?
