Anon, the Extended Mags glitch is patched. Has been for a LONG time. You're just seeing people use Extended Mags on the Shotguns and going "Oh, they must be using the Extended Mags glitch". They're not. It's the best attachment for the entire class, that's why they're using it. If you can tell me any of the other attachments are better and point out, through reasons using the weapon stats, as to why they're better then you'll be right.
