I have the same problem with mine, and I've found that the compensator slowly bends out of shape from the torque on the screws holding it on. The looser it gets, the more you have to torque it on, the more it bends, and the looser it gets. Cheap pot metal. I just fastened the front sight to the actual slide and left the piece of junk off. I think I might just take the pistol in to my gunsmith and get him to shorten the barrel and sleeve to the minimum length so it doesn't look so strange. My wife has claimed the pistol as hers anyway.
