The modular FCU configuration combines a P365XL 3.7 inch slide with an XMACRO grip module, creating a higher-capacity XL-size setup that uses flush-fitting 17-round magazines. The XMACRO grip also integrates a true 1913 accessory rail for lights or lasers.
The slide wears a durable black Nitron finish and includes front and rear cocking serrations plus an optics cut. Sight alignment is fast and clear with factory XRAY3 day/night sights, and the installed SIG Sauer micro reflex red dot adds a precise illuminated aiming option.
The striker-fired system uses a flat-faced trigger, and the polymer XMACRO grip module provides a stable, ergonomic hold. This example carries factory markings: slide marked P365 with a stylized X, chamber marked SIG SAUER 9mm x 19, and frame marked NEWINGTON, NH USA.
Included are two 17-round factory steel magazines designed to sit flush in the XMACRO grip. The package retains its SIG Sauer factory case and paperwork, with the case label dated 29-SEP-2021 and manufacturer part number 365XL-9-BXR3-TACPAC.
