Take the tank off the Shocker and it will stop leaking.
Put the tank on the Angel, put the SP gear in the trash where it belongs, and go play
Seriously though, you're asking a question in the wrong section looking for help on a gun maybe no one here owns? My first guess is to undo whatever you did and see if the problem persists. You changed the ASA and now it leaks, but it was fine before? If you changed something and now it's broken, chances are you broke it...
Edit: Are you sure it's from under the grip? I looked it up and there's nothing in there that should be leaking
