I have heard from an employee, if you purchase a can from parabellum gun store, you can use it at their range, until the paper clears.
At least you get some bang for your buck.
fullauto45 has some Thompson 30 round sticks that have been modified to fit semi auto thompsons, will these still function in an original ww2 full auto thompson?
new here, and could not reply directly to fullauto45
Thanks
