p80 mag release (g4 release)

This is something I did to have a gen4 style release button in a gen3 frame, The spring slot is a gen3 design with the size of the gen4 button on the outside. I printed one cut down just to mark the frame and two at slightly different sizes.
It is risky in the fact that I printed it, marked my frame, and filed the frame to fit the new mag release (do at YOUR OWN RISK)
Only do this if you are POSITIVE YOU ARE ABLE TO DO THIS WITHOUT DAMAGING YOUR FRAME.
I did this and just thought someone might like to look at the file.
