In about a month, I'll be buying a Glock 23. It will be ordered and then shipped to a local gunshop. I have three options, regular sights (will be replaced with something else regardless, based upon everything I hear about standard Glock sights), Glock night sights ($52 upgrade), Trijicon sights ($72 upgrade). Please chime in on these sights if you have them. This gun will be my EDC, so if they affect holster options, etc, please let me know. Thanks in advance for your recommendations.
