This P320 XFULL Pro comes from SIG’s law-enforcement allocation, making civilian examples scarce and highly sought after. The Agency Vault production ensures the same build standards and components supplied to police contracts.
The modular serialized fire-control unit lets the owner swap calibers or grip modules without tools, extending versatility far beyond a fixed-frame pistol. Fieldstripping also requires no trigger pull, adding a welcome safety element during maintenance.
A carbon-steel barrel receives a nitride treatment for added hardness and corrosion resistance, while the target crown protects accuracy potential. Coupled with the flat-faced X-Series trigger, shooters can expect a crisp break and short reset.
The black Nitron slide features front and rear cocking serrations and ships optics-ready with a factory cover plate installed. SIG X-Ray3 day/night sights combine a green fiber-optic front and tritium vials for round-the-clock visibility.
The full-size X-Series grip module sports an extended beavertail, high undercut, and wraparound texturing for secure control. A reversible magazine release accommodates left- or right-handed operation, and an accessory rail supports lights or lasers as needed.
