There's a gun shop in Marietta, Ga called The BulletStop. At the time 1986(i think), they would let you rent fully automatic submachine guns to fire on their firing range. They had quite a few, the Thompson included. If they are still around you might be able to add to your wish list.
From the NY Times 1991
The annual Spring Comdex computer show in Atlanta earlier this month
meant a booming business for the Bulletstop, an indoor firing range in
suburban Marietta where customers can rent firearms and bullets to shoot
anything they please, as long as it is already dead and fits through the
doors. The Bulletstop gave Comdex visitors a chance to vent their
frustrations by venting PC's, printers, hard disks, monitors and manuals
Paul LaVista, the owner, said about 10 groups of high-tech types came in
during the Comdex show. "I'm not a computer whiz, but one group brought
in what looked like a hard disk and blasted it," he said. "Another
bunch brought in some kind of technical manual. The thing was enormous,
about 2,000 pages. They rented three machine guns -- an Uzi, an M3
grease gun and a Thompson -- and when they were done it looked like
"It must have been quite a show," LaVista said of Comdex. "Doctors and
computer types usually have a lot of pent-up anxiety, but these folks
were dragging when they came in. When they left they were really up.
The range looked like a computer service center after a tornado."
LaVista said PC's were popular targets year-round. "People are frustrated
with them," he said. A year ago seven or eight men carried in a giant
old Hewlett-Packard printer. "I ran an extension cord to it, and just
as it started to whirr and spit out paper, they blasted it," he said.
