Hello fine folks of Glock. Just got my hands on my first ever firearm, a total noob but I’m taking all the right steps to learn to be safe and responsible. I have a Glock 17 Gen5 MOS. Really confused about exactly what fiber optic/titriam day/night sight is comparable. I saw the Truglo TMX Pro for Glock but in one post it said it wasn’t compatavle with MOS? Also I can seem to find an explanation of Low vs High. If anyone has good recommendations I’d appreciate it.
