SIG Sauer P365 XL X-Series TacPac 9mm Luger Striker-Fired Pistol – Optic-Ready, XRay3 Sights, 15+1 Capacity
The P365 XL X-Series TacPac delivers the shootability of a duty pistol in a slim, easily concealed package. Built around SIG Sauer’s serialized stainless-steel fire-control unit, this 2021-production XL pairs a 3.7-inch nitride-treated carbon-steel barrel with an optic-ready Nitron slide that accepts Shield RMSC-footprint micro red dots. A flat-faced X-Series trigger, XRay3 tritium day/night sights, and an extended beavertail grip module that feeds 12- or 15-round magazines give this pistol practical capacity and control in a carry-friendly size.
Condition
Overall Condition: Excellent – showing only faint signs of prior use or handling.
Bore Condition: Excellent – clean, mirror finish with sharp lands and grooves.
Specific Condition Notes: The pistol shows very minimal handling marks and a well-maintained bore. Please note that the slide is missing the factory optic cover plate and rear sight.
What’s Included
- SIG Sauer factory hard case (grey polymer)
- SIG Sauer P365 series owner’s manual
- 2× 15-round factory steel magazines with textured polymer base pads
- 1× 12-round factory steel magazine with textured polymer base pad
The XL-length slide offers a longer sight radius and houses front and rear cocking serrations for positive manipulation. Its direct-mount micro-dot cut lets you install a carry-sized optic without plates or added height.
SIG’s flat X-Series trigger breaks at roughly 90 degrees, promoting a consistent, straight-back pull. Combined with the extended beavertail grip and mild mag-well flare, the pistol manages recoil more like a compact duty gun than a micro-carry model.
The nitride-treated barrel resists wear and corrosion, while the Nitron-finished stainless slide and polymer grip keep overall weight low. A short accessory rail under the dust cover accepts compact weapon lights or lasers to round out a defensive setup.
Because the fire-control unit is the serialized component, shooters can swap grip modules or slides without a new transfer—adding flexibility for future customization.
