Most Helpful Positive Review Quality barrel barrel
The barrel will not fit in a P320 9mm X-Carry. It will fit in the P320 9mm Carry. The barrel length is sufficient in both guns, but the slide rear tasb in the pistols are different widths. Fit & finish are exc. There are no instructions with the barrel. I realize saying this seems like a silly thing to say, but a prudent manufacturer has to cover all the bases.

Threaded Sig P320 Compact Barrel

by Bob R, Verified Owner from TX, United States Written on September 21, 2024
I bought the Threaded Sig P320 Compact Barrel and the Threaded Sig P320 Full Size Barrel. Both are awesome and as expected. Either can be used to install a compensator or suppressor on the Sig P320 models. CAUTION to purchasers who wish to replace the Sig P320 X-Five Legion "bull barrel" with the full size threaded barrel as it doesn't fit properly. You must find a 3rd party manufacturer for a threaded "bull barrel" for the Legion.
Pros:
  • None
Cons:
  • Doesn't work with the X-Five Legion
Best Used for:
  • Compensators or suppressors
Would recommend: Yes

When in doubt, go OEM.

by RedBeans, Verified Owner from LA, United States Written on August 9, 2024
Got this to replace a Faxon threaded barrel in a Flux Raider. Was having issues with cycling while using a Rad9 suppressor. Also finding bits of copper jacket in the suppressor (but no baffle strikes); Swapped in this OEM threaded barrel and the gun has cycled and locked back consistently and I have stopped seeing copper fragments in the suppressor.

Sig OEM barrel. Doesn't get much better. I added a Griffin Arm micro comp on it and the combo is flawless!

item is good

by Brah, Verified Owner from AZ, United States Written on May 25, 2024
This is supposed to be the threaded barrel for the 3.9 inch slide according to the sig website. See pictures sold as 4.6 threaded barrel for compact not sub compact. Ok I am not aloud to post pictures. So 1/2 of an inch of barrel sticks out before the threads. I have it on the “3.9 inch sig slide.”
Pros:
  • Accurate
Cons:
  • not sure a comp woul work with my setup and this barrel
Best Used for:
  • shooting
Would recommend: Yes

Factory fit, finish, and function

by NA, Verified Owner from NV, United States Written on April 13, 2024
I recommend factory parts. Previously ordered another brands barrel and even though it looked cool I was having issues with function of the barrel in the slide. Cost for either barrel was the same.
Pros:
  • fit, finish, function
Cons:
  • None

Beautiful barrell

by J, Verified Owner from OH, United States Written on December 13, 2023
Very nice barrel. Unfortunately, it didn't fit my gun, so it has been returned. I saw the other listing with "NO LCI" in the title and this listing that did not say that in the title, at a great price , So I bought this one... Not seeing the full description below also said "NO LCI" admittedly quite plainly. So I returned it, to purchase the barrel that DOES have the Loaded Chamber Indicator, a Third option, with a heavier $$$. Once this return eventually has been completed, I shall to get the right one.

If at first you don't succeed, don't try sky-diving.
Best Used for:
  • Compact Sig 9mm NO LCI
