That depends if you are anywhere besides the anti-gun state of California where I am from. If it was here and up for sale, I would venture to say $900 - $1200. Now that is new in box with all tags hanging.
There is only one octagon shaped cauton tag that hangs from the trigger guard. The instruction booklet is still taped to the styrafoam case and has never been opened. One of the flaps was tore off the colt box, I still have it, I could tape it back on. Thanks for the help.
