New in box for a basic model, $500 - $600.
100-500 usd
100-400 USD depending on condition.
A new Glock 22 typically runs about $500. A used Glock 22 in excellent shape can range from $350 to $600. Everything really depends on the generation it is, condition (which should be perfectly fine, i mean it is a glock), if it has any extras, and if it is police issue or not. I would say a police issue in good shape would probably be worth $500-$600 easy.
