When I got home with my new Glock 27 yesterday, I opened up the plastic box they come in and found a small, brown, sealed invelope in it along with the other usual items. Having bought several Glocks before, I was curious to what this was. It had the make/model and serial # of the gun I had bought, and a testing date on it. It was signed by a Glock assoc. Inside it were two, .40 casings. This I asume are from the two rounds that were used at Glock Inc. to test fire my gun. I was just wondering if anyone else has seen this before?.... Thanks
