SIG Sauer P365XL RXZ 9mm with ROMEOZero 3 MOA Red Dot, 3.7 in Barrel, Nitron Finish, 12+1
This P365 X-Series XL pairs the 3.7 in barrel and flat trigger with SIG's factory-installed ROMEOZero 3 MOA red dot for a ready-to-run micro-compact setup. It features a Nitron-finished stainless-steel slide, a modular stainless-steel chassis within a polymer grip module, and comes with both 10- and 12-round magazines. The frame is molded 'NEWINGTON, NH USA,' and the case label is dated 22-APR-2021 with matching frame serial to label.
The RXZ configuration is the standout here: the ROMEOZero 3 MOA optic is already mounted, replacing the rear sight while retaining the green-dot TG-H3 front sight for a clear aiming reference. Front and rear slide serrations aid manipulations, and the SIG micro accessory rail on the dust cover provides space for a compact light or similar accessory.
As an X-Series P365 XL, this pistol uses a striker-fired action and a flat trigger that promotes a consistent, straight-back press. The carbon steel 3.7 in barrel balances concealability with usable sight radius, while the Nitron black slide finish adds durability and a clean, low-glare look.
Construction details are all business: stainless-steel slide over a modular stainless-steel chassis encased in a polymer grip module. The pistol has no manual thumb safety, and its materials and markings reflect U.S. manufacture, including the 'NEWINGTON, NH USA' frame molding.
Capacity and carry options are flexible out of the box. It ships with one 10-round and one 12-round steel P365-series magazine, both marked Made in USA. The listed capacity is 12+1, and the included 12-round magazine achieves that figure while maintaining the XL grip feel.
