Completely vertical like [url=http://www.improvised-engineering.com/images/Mossberg%20Fullside.jpg]this?[/url] or more of a pistol grip like [url=http://www.imfdb.org/images/thumb/7/73/Mossberg500CruiserwithForegrip.jpg/450px-Mossberg500CruiserwithForegrip.jpg]this?[/url] Keep in mind I am only asking about the forward grip, so do not base opinion on anything else pictured. Any shooters that can vouch for either one? Which one is more comfortable? [url=http://whichgun.com/img/firearms/shotguns/mossberg/500-tactical-tri-rail-adjustable-8-shot/1.jpg] This[/url] is what I currently have. 12 gauge, with a 20 inch barrel and ghost ring sights mounted. Please no rage about guns. I have one, you will not convince me to give it up. [Edited on 12.03.2012 8:32 PM PST]
