Item is good - SIG SAUER P320/250 Compact 9 mm 4.6 in Threaded 1/2x28 Pistol Barrel

This is supposed to be the threaded barrel for the 3.9 inch slide according to the sig website. See pictures sold as 4.6 threaded barrel for compact not sub compact. Ok I am not aloud to post pictures. So 1/2 of an inch of barrel sticks out before the threads. I have it on the “3.9 inch sig slide.”
