Items showing as red are my doing.
Adding a magazine safety is not a fundamental change in the gun or how it works or disassembles. They are easily removed and the gun is better for it without the magazine safety.
changing a spring clip to a tension wire is not a fundamental change in the gun or how it works or disassembles.
Adding a loaded chamber indicator is not a fundamental change in the gun or how it works or disassembles. It adds a few small parts, makes the gun more expensive, makes cleaning more difficult, and is easily removed with no function difference in the gun.
And so on with the other changes that have been made that you mention.
Today's Ruger MK series 22 autos are FUNDAMENTALLY the same as they were in 1949. You still have to take it apart by removing the nearly identical main spring housing that is attached to the pin that holds it all together. The upper receiver still has to be tapped off of the new guns until it loosens up on the all steel guns (comes off the plastic frames easier) and then has to be tapped back on to get it to line up. The hammer still has to be in just the right place and the strut STILL can get caught behind a pin in the frame if you are not careful, and you can STILL get the strut in the wrong place and the gun will not work. The BRAND NEW Ruger 22 disassembly and reassembly
STILL is the main cause of grief to the users of the gun that are either not mechanical or patient.
I maintain that the gun is
FUNDAMENTALLY unchanged. And that is how it should be. The MK series of guns are just fine the way they are.
But, what do I know? OBVIOUSLY I don't know what I am talking about. BUT, I DO know what FUNDAMENTAL means. I am not sure you do my fellow Ruger lover. I wish you the best and am amused by this nit picking but am now bored with it. I am going to go outside and shoot my Ruger 22.
