Bingo. Same with the pistols. Every show needs a gimmick, so having a few in the rental pool they can't find elsewhere is cool. Still, the ability to try before you buy is a huge selling point.
I don't know if our smaller market allows for it, but I'd ask the distributors if they have a range rental program like in the US. A discount for stocking dealers who both keep there product in stock and rent the guns so the public can try them.
