Best 4 Glock Mods, Add Ons, and Upgrades (HD+Quick)

I go through what I think are the 4 best glock mods, add ons, and upgrades that I do to all my Glocks. Find out my thought process behind each so you can make a better informed decision. See the in-depth guide with links to all tools at http://pew.link/bestglockmods

From my G17, G34, and G26, all of them have these 4 mods - extended slide stop, extended magazine release, 3.5 lb trigger, and either night sights or fiber optic sights.
