A Gen 2 Glock 19 is arguably the pinnacle of the Glock design and the ultimate expression of the form. I have one myself, and I don't think anything Glock has introduced since the Gen 2 is a true improvement on the basic design or the concept of what a Glock pistol is or should be. They have reached an iconic, almost cult status, but it is surprising that it would translate to that high a price as they are not particularly rare or hard to find.
