SIG Sauer P320 X-Series Carry Pro 9mm, 3.9" Barrel, Optic-Ready PRO-Cut Slide, Law Enforcement Vault Release
This P320 X-Series Carry Pro comes from SIG Sauer’s restricted Law Enforcement allocation, marked by the “AEU” agency vault release. Built on the modular, serialized stainless-steel FCU, it combines a factory PRO-cut optic-ready slide with a flat X-Series trigger and XRAY3 day/night sights. With its 3.9-inch carbon-steel barrel and 17-round magazines, this striker-fired pistol offers duty-grade capacity and shootability in a carry-sized package that rarely reaches civilian channels.

The Agency Vault “AEU” release indicates this handgun was produced for police and government contracts, making civilian availability uncommon. Its modular chassis allows easy swapping of grip modules, slides, and calibers while retaining one serialized component.
The PRO-cut slide features weight-reducing ports, forward and rear serrations, and is ready for optics that share the SIG ROMEO1 PRO / Leupold DeltaPoint Pro footprint. A durable black Nitron finish resists corrosion and wear.
SIG’s flat X-Series trigger delivers a straight-to-rear pull with a crisp break at roughly 90°, aiding consistent shot placement. Paired with the XCarry grip module, shooters get an extended beavertail, high undercut, and aggressive texturing for solid control.
Day or night, the XRAY3 tritium sights provide a bright green front dot and a serrated black rear for fast target acquisition. A MIL-STD-1913 three-slot accessory rail lets you add a weapon light or laser if desired.
