I basically just took various POV images of Glock night-sight setups from AR15 and here and labeled them. If any of you see any errors, or, better yet, if you have some POV Glock Night-Sight pictures to add of your own that I do not have in the album, please post them here. http://www.reddit.com/r/Glocks/comments/12zjq3/the_glock_nightsight_image_compendium/ If you are unfamiliar with Reddit, just click the link above and then click the link that says "The Glock Night-Sight Image Compendium" at the top of the page. That will link you to the album of pictures. Thanks.
