I ordered an Advantage Arms .22 Conversion kit for my Glock 22 back in March. I still have not received it. My order was placed with Topglock.com. In July, I asked customer service how many orders were ahead of me. They said about 60. At that same time, the order information for the kit I was ordering showed that there were 410 orders ahead of anyone who ordered on that day. Now the order information shows that there are 58 orders ahead of anyone who orders today. I would have thought that my order would have been shipped as that 410 backorder number worked it's way down to 58. Can anyone think of a good reason why Topglock would be giving preference to some orders over others.
