TFO's are somewhat difficult to install even by experienced gunsmiths. The bulbs are delicate and tend to break easily during installation. This requires replacement at TruGlo by sending them the gun slide. Once installed properly, they produce a fine sight picture in all light conditions.
Pros: Good sight picture in all light conditions
Cons: Yellow rear sights should be brighter
