R.C., there's no way those fellers could tell the difference between 2 7/8" and 3". Don't ask why.
Rebounding: call him again. If the locks don't have a half cock notch then it's a rebounder. Have him pull the hammer back. Bet'cha the only "click" is when it reaches full cock. Also, if he can open the gun without manually cocking the hammers it's probably a rebounder. With the hammers full down at rest, pull the trigger and push forward on the hammer at the same time. If there's any forward hammer movement then it's a rebounder.
