Thanks Dave!!
Well, it attaches to the hammer (so it's just along for the ride!) and basically covers the open area you can normally see when the hammer is in the full cock position. This is when "things" can easily fall into the action, its an open door!! The action shield curves up and back at the forward end and captures any fragment and keeps presenting the fragment each time the action is cycled. All the user has to do is turn the revolver upside down with hammer cocked and dump the debris!! Easy as falling down!!
