Most Helpful Positive Review perfect fit for M18
Perfect fit and easy swap for M18 to use a comp or suppressor. We'll in the free states anyway.
Most Helpful Negative Review Not Compatible with X-Carry
Please correct the information on this product page. This item is not compatible with the X-Carry model. I tried 2 units now and the dimensions are wrong. The protrusion above the chamber does not seat in the corresponding slide recess.

Don't bother with anything except for the real factory thing. This factory item is the real thing and works.

Threaded SIG P320 barrel

by Sparrow, Verified Owner from SC, United States Written on June 9, 2025
This barrel will be a game changer. Perfect fit had the barrel swapped out in less than 5 minutes. Ran a couple mags through the pistol no jams or any other malfunctions. So far all is well with the swap. Would recommend this barrel to other Sig shooters.

Fits Perfectly

by Kevin, from TX, United States Written on May 31, 2025
I bought this barrel so I could purchase a suppressor later. It was recommended by Sig Sauer. I fit perfectly. I put about 100 rounds through it with no problem. I would definitely recommend it for purchase.
