  • Great gun and service
    Review by gcp611on 9/2/2019
    This gun is different from the civilian production guns. Finish and trigger are different. Finish is black and not gray or FDE. The trigger is more of a mil-spec trigger that is more appropriate for duty use.
    They website is great. It is very easy to see what is in stock and what is not. The purchase was painless. The staff were very competent and answered all my questions before I made the purchase. They made the whole process very easy.. Item shipped really fast and was as advertised.
    I would highly recommend Osage County guns. They are a class act!
