This larry vickers/wilson collaboration is second to none - Wilson Combat Vickers Elite Battlesight for Glock

Great sight system for Glock. Pair this with the Wilson/Vickers narrow front combat sight and you have one of the most accurate and rapid combat sighting systems for handguns. IMHO it is functionally better than any other on the market. Studies have shown that the human eye is drawn to the simple "U" notch faster than other shapes/designs. It allows for rapid alignment with the front sight. I train regularly for combat shooting and I am definitely more accurate and faster getting on target with these sights. As these are built for combat, they are very durable and designed for one-handed manipulation of racking the slide should that become necessary. Great value for the money. Highly recommended.
