Zaffiri Precision Threaded Barrel for SIG Sauer P365-XL

This is designed as a true drop-in component. You should be able to install it yourself without any gunsmithing, though it is always recommended to verify proper function and lock-up before taking it to the range.

This specific barrel is engineered for the P365-XL. While the P365 and P365-XL share many components, the barrel lengths differ, so this will not fit the standard P365 slide.

The muzzle features a 1/2 x 28 thread pitch, which is the industry standard for 9mm suppressors and compensators. It should be compatible with most common muzzle devices designed for that thread pattern.

416R stainless steel is a high-grade material chosen for its balance of durability and machinability. Because it is heat-treated to RC 40-42, it offers excellent resistance to wear and heat, making it a robust upgrade over standard factory barrels.

Yes, the improved feed ramp geometry is specifically designed to smooth out the transition from the magazine into the chamber. This helps reduce the likelihood of feeding issues, particularly with defensive hollow point rounds that can sometimes hang up on steeper factory ramps.
