This is a straightforward upgrade path for anyone running a P365XL and wanting to mount a suppressor or compensator. True Precision engineered this barrel to outperform the factory option by refining the fitment with better radius cuts and chamfers, and designing an improved feed ramp that cycles defensive ammo more reliably. The barrel is machined from certified 416R stainless steel and finished in DLC, which uses the same coating technology found on precision machining tools for exceptional hardness and low friction.
The broach-cut rifling with six grooves handles all ammunition types safely, including cast lead loads if you reload. The 1/10 right-hand twist pairs with the SAAMI spec chamber for consistency across different ammo. Drop-in installation means no gunsmithing required, and the barrel locks up tighter than factory spec for tighter shot groups. At 4.35 inches overall length, it extends slightly past the slide, which users report reduces felt recoil compared to the 3.7-inch OEM barrel.
The Diamond Like Carbon coating significantly boosts surface hardness while adding lubricity, so the barrel stays cleaner longer. It's applied using Physical Vapor Deposition, the same process that protects high-speed CNC cutting tools. The 1/2×28 threads are standard for P365XL suppressors and compensators. True Precision includes a Viton high-heat o-ring thread protector that captures the o-ring internally, so you won't lose it when swapping between different muzzle devices.
This barrel is designed and manufactured in Georgia with USA-sourced materials. True Precision backs every barrel with a limited lifetime warranty covering operational defects. The focus on precision fitment and durability makes this a solid choice whether you're setting up a dedicated suppressor host or running a compensator for faster follow-up shots.
No. This barrel is designed specifically for the 3.7-inch P365XL, P365XL Spectre, and P365X Macro non-ported slide. It will not work on the standard P365 with a 3.1-inch slide, or on the Spectre Comp and Macro ported variants. Check your slide length before ordering.
The barrel features 1/2×28 threads, which is the standard for most 9mm suppressors and compensators. An o-ring lock thread protector is included to keep the threads covered when you're not running an accessory.
Yes. The broach-cut rifling design with six grooves is compatible with all ammunition types, including cast lead loads. This is a big advantage if you reload or use budget cast ammo at the range.
Users report tighter shot groups with this barrel due to the improved fitment, refined feed ramp, and tighter lockup tolerances compared to the factory barrel. The longer 4.35-inch length also provides a longer sight radius, which can help with precision at distance.
