I was hoping someone more knowledgeable on the subject than myself might be able to help me determine a fair price for a Glock 22. Before I advertise mine, I need an idea of the approximate value. I would rate the condition as very good, but not new. It was my former duty service weapon that I obtained a couple of years ago when the agency I work for replaced all issued with new models. The slide is engraved "South Carolina Highway Patrol" and there will be 3 15 round mags included in the sale. Thanks in advance to anyone that might provide assistance.
