I shoot a Krieghoff (Lah-tee-daa). So, all I have to do is,with the barrel removed and the opening lever in the closed position, place the outer palm of my off-hand over the cocking ears and pull the trigger twice, thus gently releasing the cocked rods.
With detachable triggers, I just remove the trigger group and slowly release the hammers with my finger, that way I can feel the springs and flip the inertial block to check if anything needs attention.
NO!!! But I do place a coin over the firing pin hole before I pull the trigger, just to give the firing pin something to hit as it were. I do this with the barrels off. It may not be the best idea to leave snap caps in the barrel for long term storage!!! break em all. Jeff
I can always re-install the barrel and forearm, If I need to place in safe for long term storage.
