I can't really tell if it is a Cansoft version or if it's full metal....
Did you notice that the hammer has started to sit higher when cocked?
That could mean that if you have a Cansoft frame, it could have started cracking....take the slide off and look for cracks.
Anyways...I had the same problem with it.
I lubed my gun. I also had to change my Cansoft midframe.
As for the second thing...I don't think that means anything, but I'm not sure. Mine does the same thing...
