SIG Sauer P365 XL X-Series TACPAC 9mm Micro-Compact Optic-Ready Pistol
The P365 XL X-Series TACPAC brings the proven P365 platform into a longer-slide, higher-capacity form that still conceals like a micro-compact. A factory-installed X-Series flat trigger, optic-ready Nitron slide, and 15-round magazines give this striker-fired 9mm practical shootability in a carry-friendly package. Made in the USA and supplied with a serialized stainless FCU, it is ready for modular upgrades without additional paperwork.

The XL-length Nitron-finished slide houses a 3.7-inch carbon-steel barrel and comes cut for direct-mount micro-red-dot optics on the Shield RMSc/ROMEO Zero footprint. Front and rear cocking serrations give positive purchase while the removable rear sight plate retains the X-RAY3 tritium sights when no optic is installed.
A flat-faced X-Series trigger breaks at approximately 5.5 lb, providing a straight pull and short reset. The serialized stainless fire-control unit allows the owner to swap grip modules or caliber-exchange kits without additional transfer paperwork, adding long-term flexibility.
Despite its micro-compact profile, the P365 XL is rated for continuous +P ammunition. The extended 15-round magazines seat flush with the X-Series grip to deliver duty-grade capacity in a slim, easily concealed package.
The integral three-slot SIG accessory rail supports lights or lasers, and the polymer grip module includes an undercut trigger guard and molded texturing for secure control.
