All right, so I actually like the stock sights and shoot my G19 well with them. However, it seems like the majority here don't like them, and switch them right out the box. Why? Is it just because they don't glow and you can't see them at night? Or are upgraded sights really more accurate? Forgive me, I am a noob and I just couldn't find enough info via search. (I think I just suck at searching this site) I'm really just trying to understand if I should upgrade my sights and if it will actually help. I don't have any friends who own Glocks so I have not shot one without stock sights. Can anyone explain to me why you do or don't shoot better with upgraded sights?
