A while back I posted about a problem I was having with my taurus tracker .44 mag revolver. The revolver could not be fired single action because the cylinder would not lock into place. Which allowed the cylinder to spin and the bullte would hit the side of the barrel and shave a piece off.
Well I sent it back to Taurus and the problem seems to be fixed. It took about 2 weeks and cost me around 25 dollars to ship.
