I`ve been pricing a glock 19 for a little while now. I`ve seen the average prices on the net, and I`m curious as to what the going prices are currently in retail. Also as I never have owned a glock persay. With buying used, what are some things I should look for so I don`t end up w/ a piece of junk. I`ve kinda still deciding between the glock , and an XD (9mm). So I suppose the same question can be applied to the XD as well. Any info is highly appreciated.
