Using a soft pry tool, start from the top near the triggers and work your way down prying, and loosening the grips until they are removed.

Double-sided tape and snaps are used to attach this part to the rear housing case. Extra force is required to remove this part. Be cautious and work slowly as not to break any plastic snaps on the grips during removal.

You can take the time to clean the rear grips now or wait till the tear down is complete.
