So my friend called me up today and asked if I would sell my Glock 23 to him. He's more of a 1911 guy, but I think I've turned him to the dark side. My question is: Do you think $400 cash is fair for a stock Glock with ~800 rounds through it? I've kept the thing in pristine shape since it was my old carry piece. I would like $500, but at the same time I am willing to part with the extra $100 if this turns him into a Glock fan. So...what say you?
