Genuine US Army decommissioned Sig M17,  part of the initial field deployment of modular handgun system pistols.  Low TF serial number, with original box, paperwork, accessories, certificate of authenticity , and Freedom Of Information Act history showing possession by the 526 BSB at Ft Campbell.  One of only ~70 know to have been returned from service with the small modular grip frame.  Good investment.  $1800

Prices firm, not particularly looking for trades, but you can throw something out of you want.  Might consider part trade for a 329pd, 340pd, Sig 1911 in nitron, S&W 1911 Sc.
