Give your micro-compact a precision core and suppressor-ready versatility. The SilencerCo® Threaded Barrel for SIG SAUER® P365 is a stainless steel, black nitride–finished upgrade engineered for reliable lockup, corrosion resistance, and repeatable accuracy in a compact footprint. With industry-standard 1/2×28 threads and an included thread protector, the AC5367 barrel turns your everyday carry into a platform ready for compensators, suppressor pistons/Nielsen devices (where legal), and other muzzle accessories—without sacrificing drop-in compatibility.
Why Choose the SilencerCo P365 Threaded Barrel
Drop-in upgrade for SIG P365 (9mm): Precision machined for reliable fit and smooth cycling.
Stainless steel construction: Long-term durability and heat resistance for high round counts.
Black nitride finish: Enhanced surface hardness, wear resistance, and lubricity with a low-glare look.
1/2×28 threaded muzzle: The most common 9mm pitch for comps, thread protectors, and suppressor mounts*.
Includes thread protector: Protects crown and threads when no device is installed.
Match-grade potential: Consistent chamber/rifling geometry supports tight groups with quality ammo.
*Always verify alignment and comply with local laws regarding threaded barrels and suppressor use.
Performance You Can Feel
SilencerCo optimizes chamber dimensions and crown quality to support reliable feeding and a repeatable point of impact across common training and defensive loads. The nitride treatment helps carbon wipe off easier, resists corrosion from sweat and weather, and keeps your barrel running slick through long practice sessions.
Threaded Versatility (1/2×28)
Add a compensator to flatten recoil and speed up split times.
Run a suppressor piston/Nielsen device for quieter, softer-shooting practice (where legal).
Keep the thread protector installed to safeguard threads during daily carry.
Safety Tip: Before suppressed use, confirm bore concentricity with an alignment rod and torque devices to manufacturer specs.
Ideal Use Cases
EDC training: Practice more with a smoother, wear-resistant barrel.
Range/competition: Pair with a comp for faster follow-up shots.
Suppressed sessions (where permitted): Standard threads simplify setup and swaps.
Custom builds: Clean, low-glare finish complements windowed or optic-cut slides.
Compatibility
Pistol: SIG SAUER® P365 (9mm Luger).
Note: Designed for the standard P365 slide length; not typically compatible with P365 XL slides due to length differences.
Caliber: 9mm Luger (9×19).
Thread Pitch: 1/2×28 TPI.
Installation (General Guidance)
Unload and clear your pistol; remove slide and recoil spring.
Replace the factory barrel with the SilencerCo AC5367; hand-cycle to confirm smooth lockup.
Install the thread protector or your chosen device; torque to spec.
Function check and re-zero if you change muzzle devices.
Care & Maintenance
Clean bore/chamber on a sensible schedule; nitride helps fouling release more easily.
Lightly oil locking lugs and contact surfaces; avoid abrasive media on the finish.
Inspect threads and devices for carbon buildup; re-check tightness after heat cycles.
