Taking down and assembling a Ruger Mark III .22 caliber pistol for cleaning is not difficult, if done in the proper steps. If not done properly, it can be frustrating. If I let a long time pass without doing it, I forget how to do it.
Items needed are: a Mark III pistol, a paper clip, as soft plastic hammer, and a needle nose plier or a small screwdriver.
If I am not mistaken, the procedure is the same for a Ruger Mark II pistol.
Step 1: Safety first
Remove the magazine. The magazine release button is under my left thumb. Hold it down and pull the magazine from the bottom of the pistol handle.
I am working on newsprint to protect the table surface and to protect the gun parts.
