The X-Series Carry Pro pairs a full-size grip module—complete with extended beavertail, high under-cut trigger guard, and molded stippling—with a compact 3.9" carbon-steel barrel. The result is a balance of shootability and concealability prized by law enforcement agencies.
The black Nitron slide is factory-milled for the PRO optic footprint, ready to accept a SIG ROMEO1 PRO or Leupold DeltaPoint Pro without adapter plates. Forward and rear cocking serrations provide positive manipulation even with gloves.
SIG’s XRAY3 day/night sights combine a high-visibility green tritium front ring with a serrated rear notch for fast sight acquisition in any lighting. Should you mount a red-dot, the sights co-witness cleanly through the optic cut.
The serialized stainless-steel fire-control unit drops into other P320 grip modules and caliber kits, letting owners convert size or chambering without another FFL transfer—an unmatched level of modularity.
Every magazine in the package is an Italian-made Mec-Gar 17-round unit, and a four-slot MIL-STD-1913 rail under the dust cover supports lights or lasers for duty or defensive use.
