The Edge is the flagship of the STI line up and is the standard to which all competition guns are judged by. It features a full length dust cover and guide rod for increased stability. The Edge comes right out of the box ready to race with a fiber optic front sight, fully adjustable rear, over sized magazine well and stainless steel ambidextrous safety. The Edge has been leading the way for over 15 years. Competition shooters have long recognized this gun for its solid, custom quality craftsmanship and reliable performance. But you do not have to be a competitive shooter to appreciate the qualities this gun has to offer.
