beside the digital_sol ion which he basically cut off all unnecessary material, most people don't do much to them. Some have drilled holes in the trigger guard to be able to more easily unscrew and screw in the middle trigger frame screw.
Be creative and have fun with a dremel or ginder. Be careful around the gauge and vertical adaptor part that you don't cut in too much.
