I'm considering a sub 2000 Glock mag 9mm. I have a Glock 19 already. I do not own a rifle and would like one. I live in Florida near the coast. My brother in law went through hurricane charley in pt charlotte, Fl. He told me about some looting that went on. Devastating huricanes bring up the possibility of outside engagements. He said I should get a traditional 223 cal rifle. I like the cost of the sub much better and the interchangable mags with my Glock. Question, What is the max range of hitting a man size targe with good optics and stock sites? I don't want the answer from the manual, but actual user data. Thanks, Dbl Tap
