the gun is taken down (barrels removed), the top lever should
always be tripped back to center. This avoids the chance of
damage, especially when transporting and shipping.
accomplish this, simply use a soft, non-marring push stick
(pencil work well) and push down on the tab located in the frame
slot where the barrel lug would sit when closed. Push down
on the tab while holding the top lever over to the right and
slowly release it back to center position.
