On the side of the revolver opposite the side that the cylinder swings out, just above the trigger is a screw. By removing that screw, you can slide the cylinder and crane out the front of the revolver. You can then clean the cylinder out as well as cleaning the forcing cone and top-strap MUCH better. Two cautions. Use ONLY a screw driver that fits precisely into the slot on the screw head. Otherwise you'll mess up the screw and they can be hard to replace. Secondly, don't lose the screw for the same reason. Be careful not to force or bend the crane when you are reassembling the revolver. Just take your time and you'll learn to do it pretty quick and easy. You don't have to take it off every time you clean the gun, but you can clean it better if you do. Good luck.
