    Norsso TIN Sig P320 X-Compact Barrel

    Posted by Randy on Sep 26th 2022

    Excellent fit and finish but pricey! All indications in the description says that this will fit a P320 pistol with an original 3.6” unthreaded barrel. Although the barrel “drops in”, it seems a bit too long for the X-Compact model, which by the way, has a 3.6” stock barrel. In my opinion, the barrel could be shortened by at least 1/8” or more so when you thread on a suppressor there isn’t such a big gap between the end of the suppressor and the front of the slide.
