Of the currently available sights I have tried, I like the TFX Pro the best. I have found that judicious application of a black sharpie on the rear sight tubes will subdue them. Besides being a the TFX being a hybrid sight, I like that the front sight is less vulnerable to damage than other FO sights I have used.
Real-world shadowing comes into play in many defensive situations. Hallways, staircases, alleys, and parking garages are examples of scenarios where you may be able to clearly identify the threat, but your sights are not well-lit. When using a WML in total darkness, all I see on any sight is the shape, but between the orange outline front, tritium and FO, the TFX Pro does a pretty good job of helping in every other lighting situation.
