Yes! excellent part from silencerco. - SilencerCo Threaded Barrel - Sig Sauer

This is a very well made and finished barrel. Bought it for a Sig M18. Very accurate and the finish is much much tougher than stock Sig barrel. If you’ve had a Sig, you know they don’t seem to be able to put a good finish on their barrels. My stock barrel literally was worn down to bare metal after hand cycling the pistol about 10 times…I didn’t even get the pistol home in the car before I was looking at bare metal on the Sig barrel hood. Couldn’t believe that Sig could get away with applying such a weak finish to their barrels, considering their guns are not exactly “cheap”. I have a Taurus GX4 that has much tougher finish on the barrel! Anyway, I’m going to run the M18 suppressed, so I ordered the SiCo threaded barrel and I love it. It sticks out farther than I expected, but I have read that because of the design of the Sig pistols it needs to stick out just a bit more to make function reliable. Logos on this barrel are tasteful and not over the top. Nothing I don’t like about this barrel. If I ever need another threaded barrel I will look at the SiCo barrels first. Great value!
