What are the differences between the Ruger Mark II and the new Ruger Mark III .22s? Has anyone purchased a Mark III?

They added a loaded chamber indicator, a magazine disconnect safety, and an internal lock. They did the same with the new 22/45 Mark III.

There have been reports of the loaded chamber indicator setting off rounds if dropped on that side.

The Mark III also has an American style magazine release versus the European style located on the bottom of the grip.
