Most Helpful Negative Review Color came in different than what was advertised
Got a solid purple barrel in the mail. Throws off the aesthetic of the gun a bit. Otherwise the precision and durability after 800 rounds was good. Easy to install and easy to clean. Accuracy seems improved but would probably have chosen a different color.

Sig P365XL Threaded Pistol Barrel (4.3)

by Brian, Verified Owner from PA, United States Written on February 20, 2026
The Faxon barrel works great. Quality product that was simple to swap out with the factory barrel. Overall, a great value compared to the recent options on the market.

The barrel works well with a suppressor. I have not noted any impact on the accuracy or function with the Faxon barrel.

Will not cycle

by LJ, Verified Owner from MN, United States Written on October 15, 2024
The fit and finish are good but for whatever reason this barrel will not cycle on my 365XL regardless of what type of ammo, I’ve tried a dozen different rounds and the most I can get is two rounds before I get a failure to feed. I don’t know if it’s the angle of the feed ramp or what. I ended up getting a a True Precision threaded barrel of the same length and it functions perfectly with hollow points or Fnh’s

BEAUTIFUL!!

by Ethan Pierson, Verified Owner from UT, United States Written on June 14, 2024
Fantasic, huge fan if Faxon, I personally use a handful of their AR barrels and have zero complaints. This is the exact same. Fit is perfect, finish is exactly what i'd expect and the looks are phenomenal. As for accuracy, i haven't put it on paper yet, so thats unknown. But its a handgun, not a precision rifle.

Works great

by Steve, Verified Owner from TX, United States Written on May 21, 2024
Dropped in with no problems at all. Added a strike fire micro circle comp and did not have to re-zero the red dot. No malfunctions and was accurate.

Nice barrel

by Justin, from CO, United States Written on February 21, 2024
This is a nice barrel at a very reasonable price. It is as advertised and after 150 rounds u have no complaints. Only wish that Optics Planet had better shipping! Took nearly 10 days to get this.
