The Reising was more balanced than the Thompson because the barrel-and-receiver-group rested concentrically within the stock. It had smoother lines in that the stock was of conventional shape, and because the cocking handle (action bar) was placed inside the forearm. In addition, it was more accurate both in semi-auto and at the onset of automatic fire, because due to it being a closed bolt gun, only the hammer and firing pin moved at the moment the trigger was squeezed, whereas the Thompson slammed home a heavy bolt and actuator.
