I just got my new thunder 9 uc pro and love it. I am not however fond of the plastic factory grips. I've been looking around a little and can't find anything on getting different grips for the gun. Understandable considering the unique shape of the grip. I'd like pretty much anything other than whats on the gun, i've been considering a hogue handall or limbsaver grip sleeve as well. Has anybody been able to find aftermarket grips or tried to put a gripsleeve on the thunder 9 uc pro?
