Thanks for the report! I've been debating one of those. I have a Mossberg 12-gauge with a pistol grip and 6.5-inch barrel and it's a blast to shoot! (Don't worry, it's registered NFA.) The Mossberg Shockwave seems like it would be fun, too. I've seen them at gun shows and local dealers, but it's not been at the top of the priority list yet. Someday it will, hopefully soon. I want one with a magazine, though.
