LOL....ill bet brother...I understand if it was sentimental value but correct me if I'm wrong but most contractors have a pile of Glocks or the weapon dejour waiting once in country.
I definitely wasn’t part of Blackwater, but I knew some guys that were. Looks to me like a Desert Warrior with different grips. Not worth it unless you were in that outfit and has some sort of sentimental value like you said. I’m not sure about that outfit, but until about 10 years ago, my unit could choose between a M1911, M9, or Glock 19. All of the Special Operations community now carry Glock 19 Gen 5 MOS with few exceptions.
