True Precision barrels for the P365 FUSE deliver noticeable improvements in accuracy and reliability over stock options. Machined from USA-sourced 416R stainless steel with proprietary broach-cut rifling (6 grooves, 1:10 RH twist), these drop-in P365 FUSE barrels feature optimized feed ramps, advanced chamfers, and target crowns designed for consistent performance with all ammo types, including defensive hollow points and cast lead.

The non-threaded version offers a clean, streamlined profile that maintains a traditional factory-like appearance while providing superior fit and finish. With its precise 4.33" overall length and target crown, it delivers enhanced inherent accuracy and tighter lockup for shooters who prefer a simple, no-fuss setup without additional muzzle devices.

The threaded version, measuring approximately 4.95" overall with 1/2x28 threads and including a high-heat O-ring lock thread protector, opens up a wide variety of customization options. It allows users to easily add suppressors, compensators, and other threaded attachments for reduced recoil, improved control, and suppressor-ready performance, making it ideal for those looking to optimize their P365 FUSE for specific shooting needs.

The True Precision Duty slide for the 4.3" P365 FUSE combines sleek aesthetics with functional upgrades that improve handling and sight acquisition. Cut from 416R stainless steel, this optic-ready P365 FUSE slide features lightweight side windows, a top-milled pocket, aggressive scalloped front serrations, and angled rear serrations for confident manipulation under stress. It comes pre-cut for RMSc-footprint optics (compatible with Holosun 407K/507K, Sig Romeo Zero, and similar models) and works with standard P365, XL, and FUSE lowers. The design maintains full compatibility while reducing weight where it matters and providing a refined, professional look that elevates the entire pistol for P365 FUSE owners.

Effective recoil management transforms how the P365 FUSE shoots, especially during rapid fire or suppressor use. The True-Lock compensator uses a patented locking system and a 6-to-1 port-to-bore ratio to dramatically reduce muzzle rise and felt recoil across various ammunition types. It attaches securely to threaded barrels and delivers consistent performance for P365 FUSE compensator setups.

For those preferring a lower-profile option, True Precision micro compensators (including Y-Type, S-Type and Cobra designs) offer excellent recoil mitigation in a compact, snag-free package. Both styles are engineered for the FUSE platform and provide meaningful control improvements while keeping the overall footprint suitable for everyday carry or range work with your P365 FUSE.

A quality trigger upgrade can make a significant difference in shooting comfort and precision. True Precision flat triggers for the P365 FUSE provide a crisp, consistent pull with excellent reset feedback and a flatter face that promotes straight-back pressure. Constructed with premium materials and designed as a direct drop-in, these P365 FUSE triggers reduce perceived travel and stacking while maintaining full safety and reliability. Shooters often report improved control during strings of fire and greater confidence on the range or in defensive scenarios.

The True Precision magwell brings competition-inspired speed to the P365 FUSE without compromising concealability. Precision-machined from solid billet stainless steel and available in all of our coating options, this flared P365 FUSE magwell features a funnel design that guides magazines home quickly and reliably even under time pressure or with gloves. It is specifically fitted for the FUSE and XMacro platforms and offers a refined match to stainless or two-tone builds with added surface area and smooth contours that improve reload efficiency while maintaining the pistol’s balanced feel.

The extended stainless steel mag release pairs perfectly with the magwell to deliver positive engagement and faster reloads. Machined from stainless steel for superior durability and corrosion resistance, its extended profile provides easier reach without being overly aggressive, making it ideal for both large and smaller hands. This simple yet highly effective upgrade reduces the chance of fumbling during reloads and enhances overall ergonomics and shooter confidence on the P365 FUSE

Combining True Precision components allows you to create a cohesive, high-performing P365 FUSE tailored to your specific needs whether for competition, home defense, or suppressed range use. Matching stainless finishes across the barrel, slide, magwell, and mag release creates a clean, professional appearance, while mixing threaded barrels with True-Lock or micro compensators delivers excellent recoil control for your P365 FUSE upgrades.

Consider your priorities: a suppressor-ready setup with a threaded barrel and optic-ready slide for night or tactical use, or a smoother-shooting carry option with a flat trigger and flared magwell for faster reloads. Because all parts are designed to work together seamlessly on the FUSE platform, you can build with confidence knowing the components are engineered for precision and reliability.
