The release trigger fires only one time when the trigger is released. In order to make the gun fire again, the shooter must pull the trigger again to set it.... and then release it. The primary purpose of release triggers is to treat the affiction called "flinching". Release triggers usually work to cure (or at least greatly reduce) flinching, but in a small percentage of cases, they don't cure the flinching problem.
