Simcha, I've been running a 391 for about two years as a 3 gun shotgun. It loads easy with an opened up loading port, and the barrel can be shortened and chokes reinstalled if you're into that sort of thing. Don't bother with the spare barrel, for what they cost you can just buy a second gun... Nordic components makes charging handles and extended tubes for them as well. the oem stock is stupid long for run and gun stuff, but the tungsten rod in it is for weight and can be discarded. Mine is wearing a magpul SGA stock (had a machinist make a remington pattern tang that threads into where the tungsten filled rod used to be. It's a hackjob, but an amazingly shootable gun.
