I called Glock customer service this morning to return a G17 Gen 2 with a crack in the frame for warranty work. The customer service representative said that I must have an FFL send them the gun. I asked why I could not send it directly and he said that's just the way it is. I understand that Glock would need to send the repaired gun back to me via FFL as it will have a new frame with a new serial number and need to be registered and DROS'd to me but I cannot understand why I can't send it to them directly. Anyone have a similar experience or know why this is? Thanks.
