My P-09 shoots a bit low when I line the sights up straight across. I've only been to the range with it twice but I've noticed it both times. I'd like to replace the sights with a fiber optic set (used them on other guns, love them) so if anyone can offer any information on the appropiate height, installation, etc I would appreciate it. My front sight has a 3 stamped into it. Does that mean anything?
