Worth every penny - Trijicon HD Walther P99/PPQ/PPQ M2 Heavy Duty Night Sight Set w/Yellow Front Outline

This is my 3rd set of Trijicon HD Night Sights. No problem acquiring a sight picture at night with these beauties and they are just as good during the day. They are much better than the polymer sights that came on the Walter PPQ and not as much air space between the back blades. Easy to install and did not require a sight pusher. Just a small flat screwdriver, 5mm small socket, and I think a 1.3 mm hex wrench. Plenty of videos online to help you install them.
