Hey folks. Im thinking about buying one of these barrels from the Glock Doc: http://www.glock-doc.com/_wsn/page8.html I know his customer service is A+ and have heard some good things on the barrels however I have not ever heard anything on the Glock 20 barrel. Hes got em for 79 dollars each in factory length, extended ported and extended threaded. I am thinking of either the factory length or extended ported. I dont know what the plus side would be for the ported. The barrel will only be used for target use. I am mainly wanting to be able to load lead bullets to medium to full power loads and not have my brass end up with smiley's on them. Any help would be great. Thanks Take Care "duck"
