I just received a replacement G27 from Glock about a week ago. I sent mine in to Glock and they determined it would cost more to fix than replace. They offered a refurbished one or a new one. I took the new one. However I just noticed the prefix is NCR. I looked up that serial number and it was produced March 2009. The test casings included with the gun are dated 10-16-12. So Glock had this gun in stock from March of 2009 but just test fired it in Oct 2012? Or did I get a refurbished gun when I was supposed to get a new one?
