Most Helpful Positive Review Great OEM barrel
Sig Sauer makes quality products, and this OEM barrel is no exception. It dropped right into the slide and fit and functioned perfectly in my P320 Compact. I've fired 350 rounds through it so far with no malfunctions whatsoever. In my experience, it's as accurate as the non-threaded barrel that came with my pistol.

It works...but not well!

by Andrew, from TX, United States Written on May 8, 2018
I installed it and threaded my suppressor and was having FTE issues and thought were it was my subsonic ammo so loaded 115gr supersonic ammo still had FTE issues. Getting annoyed took the suppressor off and fired a full of 115gr magazine no problem loaded a second magazine of 115gr and after 3 rounds get a stove pipe?!?!?! After that replaced with factory non threaded barrel shot 50 rounds no problems! Don’t know what the issue is it says it’s a factory OE threaded barrel?!

  • None

Nice Barrel

by Bill, Verified Owner from IN, United States Written on September 7, 2017
This is a good barrel for the P320 compact. It dropped right in, and has worked fine through 500 rounds so far. Some complain about it sticking out too far, but I see the extra length as a positive. It sticks out just far enough that my streamlight tlr-2 doesn't get all gunked up with carbon from the muzzle flash. My only complaint is that it is left hand threads, since most silencers have right hand threads on the piston end-cap. The problem is that you can't just grab the middle of the can to tighten it without loosening the piston end-cap. Maybe they did that to prevent over-tightening of the piston end-cap and damaging the threads? I see this as just a very minor inconvenience, though.

P320 replacement barrel. Great fit!

by Crusty Leatherneck, from TX, United States Written on June 16, 2017
I ordered a threaded replacement barrel for my SIG P320 compact. It was the best deal that I could find on the internet. Shipped fast. Dropped right into the weapon. Cycled through 400 rounds flawlessly. It was definitely a good buy.

A Sig Factory Threaded Barrel

by techster82, Verified Owner from KY, United States Written on October 12, 2016
What more can I say? Its a brand new Sig factory threaded barrel for the P320 compact. Fast shipping and just what I was looking for to host my suppressors. 13.5x1LH threading is pretty common with european companies.
