Don't know how to paste URL's here via my droid or I would put a link here. Sorry. Search You Tube for: Gunny Glock 18 In search results it's 3rd video down. AMAZING how much flex happens when a pistol is shot! I had no idea! But apparently Gaston Glock did, and incorporated material to work WITH it instead of fighting against it. Brilliant! Video is of a full auto G18 Once again, sorry for no link...maybe someone less 'tech-tarded' than I can place it in this thread.
