I'm wondering which of these would be the best? I have absolutely no experience with any night sights so I have no idea. I haven't found anything about the differences between them. $501 --- Base Pistol $527 --- Glock Night Sights $561 --- Meprolight Nights Sights $576 --- Trijicon Night Sights Again, I have no idea which to get, so rather than just pick one, based upon price or a name I ask for opinions from those who know. Any way I stack it they're still quite cheap when you buy them on the gun compared to retrofitting them. Thank you!
