Do they sell forarm grips(like the vertical AR style grip) for the Remington 1100? I want to turn the shotgun I have into a tactical shotgun. I've seen a pistol grip you can buy for it but no vertical forearm grip. The reason I want a forearm grip is I have a little bit of tendinitis or at least I think thats what it is. My left bicep will sometimes get tight and having a forearm grip would help. I have the 1100 because someone sold it to me for cheap. Too bad there doesn't seem to be a lot of after market parts for it.
