Why would you think that you might need to send your Tomcat back to Beretta for repair? What do you think they are going to be able to "fix"? With the the 24/7 "Big Dot" sights, the "AlleyCat" is what it is. It is not a target pistol. As long as you know the gun shoots consistently 6 to 8 inches low at 3 yards and you can get consistant groups, that is all you need to know. Adjust your point of aim to place the point of impact where you want it to be. The regular sights on a Tomcat are small and hard to see. It is more of a point and shoot type weapon. It sounds like you have figured out where to point it and that is half the battle. Good luck.
