The price of a new Glock from the importer (Smynra, GA) is about $230.
They get over double on them.
I know because a few years ago I was shooting a buddy's Glock .40 cal and it blew up in my hands. I was using UMC ammo, but the factory said that I was using reloads, so I sent them in the rest of the box that I had.
Their response was that there was not enough left of the chamber to tell if I was really using what I said, or reloads as the believed, so I had to eat the cost for a new gun at their cost which was $230.
I'm just lucky to have all of my fingers.
That's why I won't buy or shoot another Glock .40, because they have an unsupported chamber (WTF ever that means....)
