i have found a place that takes trade in firearms from law enforcement agencies. where they sell police trade in service guns. the have glock 22's with two mags for under $400 after tax and other fees. the guns have some carry wear im sure. my issue is how much have they been fired? i feel like these being service weapons they maybe in rougher shape. i know glocks are tough, but im not sold on this yet. what do you guys think?
