Hi Glock folks! I bought a “new” G19 Gen 4 1 of 1000 Navy Seal Foundation from a gun show. It’s beautiful and I love it, but I now do not think it was new gun. It came with the box, 3 mags, extra back straps and all the paperwork sealed in the envelope. The gun had a zip tie thru the barrel locking the slide open that could not be removed until leaving the gun show. I noticed that the gun looked to have a lot of oil on it, more than I ever noticed on my other new Glock’s. But when I got the gun Home and broke it down, there was none of the copper lube. I felt then that it was not a new gun. As I cleaned the new gun, I found some engraving on the barrel. 2 letters and one number. It looks like someone engraved it at home. I registered the gun with Glock without a problem. BUT is this a new gun I purchased or a used gun?
