Several of the firearms that we had rented to shoot were malfunctioning. The Thompson would fire through the majority of the magazine after you took your finger off the trigger. When the range officer was told he told us to point the gun down and keep trying. We then watched them hand the same broken firearm to multiple other people who were also experiencing the same problem. Before we left the store we had to talk to several employes before they would finally take it off the shelf and have their smith work on it. It's unfortunate that a range would behave in such an unsafe manner, I can think of few things more scary then putting an uncontrollable automatic weapon in the hands of someone that has never handled a gun. It didn't help that no refund was offered even when we informed them of just how dissatisfied we were. I would be very very concerned shooting in this environment.
