Glock also has excellent customer service. I sent in a 28 year old Glock 19 for a refresher since it was a PD gun with many thousands of rounds of 124 grain Gold Dot]s, not to mention what the original owner might have put through it. They got it on 12/22, called me on 12/22, and the gun was back in my hands on 12/24. Virtually every internal component replaced other than the barrel and locking block, and shipped it back in a new factory hard case. Other than the new night sights I requested, they charged me not one penny. This is a company that advertises a 1 year warranty for original owner.
