I KNOW THIS POST IS REALLY OLD.  However, I needed to ask how this is still holding up.  I HAD THIS EXACT SAME PROBLEM WITH IT AND THEY ENDED UP KEEPING THE GUN AND JUST GIVING ME MY MONEY BACK WITHOUT AN EXPLANATION?!  It was a crazy experience as I had sent it in 3 times to remedy.  This link takes you to my story with DW Kodiak.
