Looking to trade my Glock 21 Gen 4 for a Glock 30 S or sell for $500.00 (Firm). My G21 is in very good shape. I have fired about 50 rounds through it. I bought it used. When I got the pistol it still had the factory lubrication in the slide. There is no holster wear on the slide stop. I haven't carried it and it doesn't look like anyone else has either. I have installed TruGlo Fiber Optic Sights on it (not tritium). The gun will come with a Blackhawk holster, standard 3 magazines and the box containing the usual goodies. This is an early model and only had two different back straps (the extended beaver tail back straps not included). I am located in Portland area and will not travel a long ways (Portland metro area only). FTF only, be prepared to show me an Oregon ID and CHL.
