I see what looks like a glut of glocks, m&ps, and sigs on the market in .40 cal as many departments move to 9mms. I don't really need a new caliber, but I am always interested in cheap stuff. What are these guns like? Condition? Anything about them different from what I might see in a standard commercial version? I would guess that I would see guns that are carried a lot and shot little, correct?
