the gun of the year is the Remington 1100 G3 in 20 gauge. It is an awesome gun! the other guns can vary depending on what each RD ordered for that particular banquet. Most will have the Wetherby shotgun, tri-star shotgun and most likely the Stoeger o/u. All of these will be in the 12 gauge variety. I hope that helps.
Probably the coolest gun that will be there is the Judge by Taurus-chambered to shoot 3" .410, it is a beast. there is also a .308 tactical rifle that comes with a scope and bipods.
Most will also have a .380 made by ruger that has been difficult to come by since the new administration took office.
