Can it handle +P ? Expert Answer

The manufacturer does not state if the True Precision Pistol Sig P365 XL Barrel can handle +P ammo. I recommend contacting True Precision in regards to that information.

Fine barrel but a slow one by Phil, July 26, 2022
Nice barrel, the o-ring is a great addition. I bought it for more velocity in my P365-XL, with the added 3/4," and found it consistently no faster than my standard 3 3/4" XL barrel, sometimes slower, with 5 different ammos, including 115-gr WIN pract...

True Precision by Allen, April 18, 2023
This True Precision barrel is a great upgrade to the factory barrel. Throw on a mini comp, and you have a great shooting little 9mm. On my P365 Macro you get a compact pistol, that remains very concealable. I added a 507k from Holosun and paired with...

Exactly What I Wanted! by Andrew, Verified Owner, February 26, 2024
I've been running the True Precision Threaded P365 barrel for a couple years and it's performed wonderfully. Recently I've made the switch to the XL slide length and I still want to run my compensator so this seemed like a perfect choice. The added ...
