MKIII 22/45 trigger claw?

[banjogun]

On the back of the trigger of the MKIII 22/45 there is an integral piece, that sticks out that looks like a claw or hook. When the trigger is pulled, it seems to rotate back and upwards into a hole in the magazine. Does any body know just what the purpose of this is?

I don't think it does anything. The top of the trigger pushes the disconnector which releases the sear. See
