Take off the grip and take off the front trigger guard screw and you'll get it off. Check my my .357 RS2/Blizzard tuning thread for what needs to be done to the trigger sear. You may also have to shorten the blade a bit, it locked to the guard in my .45 X2.Edit, there might be a rear screw for trigger guard as well but you'll figure it out once the grip is off.
