I'm sitting here in a state of confusion. I decided to give the Mark II a cleaning tonight. I had planned on cleaning it as best I could without breaking it down. While cleaning what I could reach I just couldn't help myself and I decided to go ahead and disassemble the gun. Expecting the worst I printed a copy of Spyder2's takedown instructions and proceeded to disassemble, clean and then reassemble the RUGER MARK II without the slightest problem. I just can't believe how easy it really was. I'm afraid maybe it was too easy, but everything seems to be working fine. I didn't need a rubber mallet or anything. It defense of those who have had so many problems with this process I must admit that the gun appeared to have been taken down previously (I can see some scratches around the takedown lever). The friend who owned this gun previously was not the original owner. The original owner evidently had down this regularly and none of the parts were stuck or hard to deal with. It was as easy as any of the other handguns I have owned.
