I'm selling a SIG 550 for a collector (who also owns a SIG 551) who would like to remain anonymous. This gun is considered new in box, as it has never been fired. Comes with all original factory packaging, manuals, paperwork and accessories. Comes with 5 original clip-together mags. Serious inquiries only, please. Serial number 2XX. Can be shipped to buyer's FFL, but I recommend coming to Mesa, AZ to pick gun up in person! Please contact me at firstname.lastname@example.org if you are seriously interested. Price is $15,000. Thanks for looking.
