I would like an opinion about fiber optic sights. I recently had my a fiber optic sight installed on the front while my rear sight is a Heinie sight on my G17. Has anyone had experience using fiber optic sights shooting either Indoor or outdoor GSSF events? Do you like them better than using Heinie sights for both front and back? I am wondering whether I have to get used to it, or if I want to go back to using just my Heinie sights for front and back. Those were great to use and I don't know if I have to get used to this fiber optic front sight or if all of this is in my mental state - my head. Any opinions are greatly appreciated. Thanks for any help.
