Yes I stand corrected. I disassembled the mag release and there is a small steel insert at the top. My first inspection from the top looked liked it was plastic.
I have been following this post for awhile and would like to add my observation off the problem. Im not a gun smith nor do I recommend altering your gun or parts in any way.
So I have attached two pictures. The first picture shows the magazine release, release catch and release tension bar...
