GTA IV Glitch- Automatic Shotgun

This is a very easy glitch that can be done only in multiplayer. First what you need is a submachine gun and a shotgun. Then pull out your submachine gun and take cover. From the cover look perpendicular from the wall. Shoot the submachine gun and while holding the right rigger switch to the shotgun. The shotgun will now mimic the submachine gun and shoot its shells fast. You can do this with any gun; you can shoot your AK-47 like a pistol or like a shotgun. Later in the video I shoot the pistol like a submachine gun. Enjoy.
