The grips are held on with 2 allen head bolts from the bottom, under the trigger. The trigger is glued in. Best way to get the trigger out. Wrap a socket extension in masking tape, so you dont mess the chrome, or wrap it in sheet. The longer the extension the better. Put it through the trigger and either tap it down with a hammer, or just push it hard. Make sure the gun is supported on the ground or something.
