    3.6” Sig P320 threaded barrel

    Posted by Perry Harman on Mar 4th 2023

    I don’t know where to start. Norsso is awesome to deal with. They are some of the nicest, most accommodating people in the industry. The quality of the barrel that I purchased is second to none. The firearm function is so much smoother with the Norsso barrel. I had not heard much about Norsso and was hesitant to buy. I’m so glad I did. I will definitely be purchasing more items from this top notch company!

    3.6" Threaded Barrel Satin Stainless

    I purchased this barrel for my xcompact build. Paired with a compensator and after just over 200 rounds, the barrel still looks like it just came out of the package. I own a few NORSSO products and have not one complaint. Their stuff is 5 star quality and performance for sure. Their customer service is, by far, the best out there. I will be a long term client for sure.
