have tried other manufacturers night sights, trijicon is my favorite. clear tight sight picture. tritium inserts give good illumination.
you either need to get a gunsmith to install or do like i did and get a sight install tool, i soaked everything down with wd40 and had zero problems getting the old ones off or new ones on. YMMV
Pros: easy to pick up sight picture in low light
Cons: gunsmith or tool to install
