You know, Jerry Reed, 70s bad guy movie shotgun. 6" ish barrel and a pistol grip, maybe even a stock like the the bottom two in pic 2. Has anyone done one? I'm running into walls on which shotgun to use. I don't want to lose reliability, and it seems like mose SXS's and O/U's now have an extended forearm. I'm not stuck on it being 12ga. I'm open to 20ga and 410.. Heck, I'm not even stuck on it being SXS. There aren't enough O/U thumpers in the world.
