My G29 has started to malfunction again. It is the same problem I sent it in for a few months ago, spent case stuck firmly under the extractor. I am now going to request that they replace the pistol with a new one. Has anyone had this done before? Do they take the serial number tag off the frame and just slap it on another pistol? Or will I have to pay for another background check (TN CHLs do not exempt the holder from TICS fees)?
