Yeah, Mathub, the little metal plate with the hole, I was going to make one as they look pretty simple. Just a matter of finding the time.
ColSanders, I had to cut a bit out for the ambi safety, aswell as deepening the hole on the underside of the grip so that the grip screw things (forgotten the name) could go into it so the grips would sit flush with the frame. Also I had to enlarge the bottom grip screw hole on the underside of the frame as they did not line up exactly with the grip screw things. They are the first set of real steel grips i've had that needed to be modified.
