Just Monday I posted my great luck in finding a G30S plus plenty ammo both target and SD. Well it seems all news was not good news. Due to my lack of reading the Trijicon night sights are for the 20/21/29/30 and we all know the 30S is the same slide as the 36. The sights were installed with my main gripe being the front sight I am able to manipulate by hand. Further research revealed the front sight nut is shorter for the 36 vs the others, which is why I am able by hand to manipulate. Well here are of a few pics of the wrong sights to purchase/install. GL04 = Glock 20, 21, 21SF, 29, 30 GL12 = Glock 36, 30S Wanna kill these ads? We can help!
