Just sold one on consignment with one mag, and in good condition for $325. If one you are looking at is good to very good condition, then my guess would be $299-399 range. Cosmetic wear can affect the value to some extent, and is what the buyer first sees, but internal wear(barrel, feedramp,springs, etc.) may be left to a qualified person or previous owner to asses the wear factor. Others on the forum with more experience may give you other insight into helping you determine what you are looking at with this gun. zorro49
