ZAF SIG P365 3.75" Threaded Barrel Black BA-P365-TH-BN (UPC 810220064948)

The ZAF SIG P365 3.75" Threaded Barrel Black BA-P365-TH-BN (UPC 810220064948) is a high-performance aftermarket barrel designed to upgrade the popular SIG Sauer P365 pistol with suppressor-ready capability and improved ballistic performance. Manufactured by ZAF, a trusted name in precision firearm components, this extended 3.75-inch threaded barrel offers significantly better muzzle velocity, enhanced accuracy, and the ability to mount 9mm suppressors on the compact P365 platform. The SIG P365 is already one of the most popular micro-compact 9mm pistols on the market, and this ZAF threaded barrel takes its performance to the next level by allowing users to add sound suppression while maintaining the pistol’s slim and concealable profile.

Unlike the factory SIG P365 barrel, this 3.75-inch threaded version provides noticeable improvements in velocity and recoil management, especially when paired with a suppressor. The durable black finish gives the barrel a clean, tactical appearance that matches most SIG P365 pistols.

Suppressor-Ready Threaded Design

The most important feature of the ZAF BA-P365-TH-BN is its threaded muzzle. This allows SIG P365 owners to easily attach 9mm suppressors, transforming the pistol into a much quieter and more comfortable shooting platform. The precision-cut threads ensure a secure fit with most popular 9mm suppressors on the market. Whether used for home defense, tactical training, or recreational suppressed shooting, this threaded barrel gives users the flexibility to reduce noise and muzzle flash while improving overall shooting comfort.

Extended 3.75-Inch Barrel Length

The 3.75-inch length of this ZAF barrel is significantly longer than the factory SIG P365 barrel. This extended length provides several performance advantages, including increased muzzle velocity, improved accuracy at longer distances, and better overall ballistic performance. The additional length also helps reduce muzzle flip and felt recoil when using a suppressor, making the P365 more controllable during rapid fire. This makes the pistol more effective for both defensive and recreational shooting applications while still remaining relatively easy to conceal.

Durable Black Finish

The black finish on this ZAF threaded barrel provides a clean, professional appearance that matches the factory look of most SIG P365 pistols. The finish offers good resistance to wear, scratches, and corrosion, helping protect the barrel during regular use and exposure to the elements. This makes it a practical choice for both concealed carry and high-volume range use.

Precision Machined for Reliable Performance

The ZAF BA-P365-TH-BN barrel is manufactured with tight tolerances to ensure reliable feeding, extraction, and consistent accuracy. It is designed to function seamlessly with both factory and aftermarket slides on the SIG P365. Shooters can expect smooth operation with a wide variety of 9mm ammunition, including standard pressure, +P, and defensive loads. The barrel maintains proper lockup and delivers the enhanced performance that comes with the extended threaded design.
