Target acquisition is by far, the most important aspect of defensive shooting. When you are drawing down on a target you want to be able to acquire it fast and accurately. Each shooter will have their own personal preference, so it is important to select a sight that fits your unique shooting habits. There are several sight options available including fiber optic, tritium, and a combination of the two often referred to as TFO (Tritium Fiber Optic)
