THE 5th HAND,
I am not sure if what RK told you is what you were looking for... but since he wrote all those good instructions already, I will approach the other possible meaning of your question and that would be ther removal of the takedown lever from the frame...If that is your intent, it is a very simple process... simply do everything that Roadkill told you to do, and once you have removed the upper half of the gun, then with the lever in the open position, pull hard with your fingers (DO NOT PRY ANYTHING with tools) to the left side of the frame and the lever should come directly out of the frame. The small wire spring is intended only to keep the lever in the frame when the gun is partially disassembled. If you have any further questions... just ask and someone will come to you assistance.
BTW, if your location is really "Pacific Ocean" then make sure you use plenty of rust preventative during the reassembly process
