Hi, I am new to GT and just bought my G27 Sunday. I have been reading the forums for days and couldn't post so I am kind of a ministalker for you ladies and gents. I have been shooting for 13 years (I'm 21) and have a few firearms. I've heard a lot of opinions on nightsights and I am leaning towards yellow back and green front, tritium sights. Anybody have opinions on this?
