Would you be interested in trading your Glock 21 for a Springfield Armory 1911 Ultra Compact duo tone with 3 dot sights. This one has the 3.5" tapered bull barrel system (no bushing) with adj trigger and beavertail grip safety and extended pacmyer slide release. It has a nice pair of cocobolo grips. It comes with 1 original mag a 3 Chip Mc shooting star mags, the original blue case and a very nice Tex Shoemaker basketweave holster. The slide is blue and the frame is a matte stainless finish. There is one large scratch by the trigger on the left side but other than that the gun is in very good shape. Let me know what you think.
