View Full Version : G21 2 gen
Evening JR, 2 gen 21, 2 pin or 3 pin? Thanks for your time,
You can easily identify your self...
Look at the trigger pin.... That's one
Is there a small pin above the trigger pin? If so, that is the 3rd pin.
FYI: The second pin is in the rear most part of the grip. It is the trigger housing pin.
