The frame on my pre-series 80 Commander has developed cracks in the dustcover in front of the slide rails. I have carried this piece for years and used it in training over 3000 people for thier CCWs in Arkansas. I carry Colts exclusively (my pocket pistol is a Colt Agent) and I don't want to resort to an aftermarket frame. Is it posible to send this one in for repair or to obtain a Lwt Commander or Officer's frame as a replacement? Any help/advice you could give me will be greatly appreciated.
