This is the only shotgun that you can dual wield, and I must say it's pretty fun. The HS10 is semi-automatic like the Spas 12, and while it only has a 4 round magazine (or w/e you call it on shotguns), when dual wielding you have 8 shots in total. I find that if you shoot both at one time while in a decent shotgun range of the enemy you'll bring him/her down every time. I strongly encourage nay other shotgun enthusiasts to try this gun with the dual wield attachment.
