A friend of mine bought an STI Edge. He let me shoot it for the first time last week. Folks, I don't know the first thing about STIs, what make them 2011's or anything else for that matter. But I can tell you that this gun in 45 was absolutely unbelievable. I shot better groups with it than anything I've ever fired. I am not a good shooter by the standards of the good marksmen on Addicts. But this thing was ridiculous. All shots were touching each other except two which were my fault. Its hard to imagine that a pistol alone could turn this old fatman with shakey hands, and weak eyes into a competitor . I don't understand it, but I've been bitten. I gotta tap in here to learn more about these things.
