Every mcarbo part available is installed on this one. Used it as a truck gun for a long time but it's since become a safe queen. It shoots flawlessly and is a multi mag model that is currently set up for a Beretta m9/92. Comes with custom case, sling, 2- 20 round mags, 1- 17 round factory mag, streamlight polytac light and sling. Can be switched to S&W M&P 9, Sig 320 or CZ 75. You will just have to buy a new mag catch from mcarbo and switch it out. I'm asking way below what I have invested so no low ball offers will be accepted.
