SIG P365XL – Threaded Barrel – 9mm 1/2x28 Black Nitride


PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

This Zaffiri Precision threaded barrel is built for the SIG Sauer P365XL in 9mm and gives the longer XL slide a 1/2x28 threaded muzzle setup for compatible compensators or suppressor use where legal.

It is machined from 416R stainless steel with a black nitride finish and built as a drop-in style replacement barrel. This is the P365XL barrel — not the standard P365 barrel. That one inch of wrong thinking creates returns.


Fitment

  • Fits SIG Sauer P365XL 9mm pistols.
  • Threaded muzzle uses common 1/2x28 thread pattern.
  • Manufacturer notes this barrel has a Loaded Chamber Indicator notch.
  • Threaded barrels may be restricted in some locations. Check your local laws before ordering.

Does NOT Fit

  • Does not fit the standard SIG P365.

What It Does
