Description

True Precision engineered this barrel to be a straightforward upgrade for your P365XL. It's machined from certified 416R match-grade stainless steel and finished in a durable gold titanium nitride coating. The proprietary broach-cut rifling design improves accuracy potential while maintaining reliability with any ammo type, including cast lead rounds. This isn't a barrel that compromises between looks and function—it delivers both.

Advanced Engineering for Tighter Groups

The chamber and feed ramp get special attention in the design. A polished and widened feed ramp reduces feeding inconsistencies compared to the factory barrel, and the overall fit is tighter than OEM specs. Buyers report cleaner, more accurate shooting with this barrel, especially when paired with defensive ammunition. The match-grade tolerance means better lockup and more predictable bullet placement from round to round.

Threading Ready for Your Setup

The barrel comes threaded with 1/2×28 compatibility, opening up options for suppressors and compensators. A Viton high-heat integral O-ring lock thread protector ships with the barrel to keep the threads safe during carry or storage. The gold TiN finish resists corrosion and holds up well to the carbon and fouling that comes with suppressed shooting.

Drop-In Installation

This is a true drop-in design. Most people swap it during a basic field strip without gunsmithing or special tools. The 3.7-inch barrel length keeps your P365XL's compact handling intact while the overall threaded length reaches 4.35 inches. The design does not retain the loaded chamber indicator cutout, which actually helps keep pistol-mounted optics cleaner by preventing powder blowback through the LCI peephole.

Frequently Asked Questions

Will this P365XL barrel fit my pistol without any modifications?

This is a true drop-in design for the P365XL 3.7-inch, P365X-MACRO (non-ported slide), and P365XL Spectre models. Most shooters install it during a basic field strip without tools or gunsmithing. Note: If your model has a loaded chamber indicator, you may need to remove or shorten it for proper fit—True Precision covers this compatibility detail on their site.

Can I use this barrel with a suppressor?

Yes. The barrel is threaded with 1/2×28, the standard for 9mm suppressors and compensators. It includes a thread protector with a captured O-ring that keeps the threads secure and safe when running suppressed or unsuppressed. The gold TiN finish also resists carbon buildup from suppressed fire better than plain stainless.

What's the difference between match-grade and factory barrels?

Match-grade barrels like this one use tighter tolerances, cleaner rifling, and polished chambers and feed ramps. You get better lockup, more consistent shot placement, and more reliable feeding across different ammunition types. The 416R steel and proprietary broach-cut rifling specifically improve accuracy potential compared to stock barrels.

Does this barrel improve accuracy over the factory barrel?

Most shooters see noticeable improvements thanks to tighter lockup, polished feed ramp, and cleaner rifling. That said, your ammo choice and shooting fundamentals still matter more than any single part. The match-grade design gives you the best foundation to deliver accurate groups if your skills and ammunition are there.
