The small P320 X-Series grip module delivers a refined full-size platform for anyone wanting tighter ergonomics without sacrificing what makes the P320 modular. Drop your firing control unit into this polymer frame and you've got a complete P320-XFULL conversion in 9mm, .357 SIG, or .40 Auto.
This isn't just a regular grip module. The X-Series design features more aggressive laser-engraved stippling for enhanced traction and improved grip control during extended shooting sessions. The small circumference profile fits hands that find medium and large grips too thick without compromising the full-size slide compatibility or magazine capacity you get with a proper P320 full-size platform.
The frame is fully compatible with Sig's extended magwell and internal grip weight systems, though these components aren't included. This compatibility opens the door to custom building or future upgrades if you decide to enhance recoil management or aesthetics down the line. The modular design means you can swap this frame between different slides and caliber combinations as your needs evolve.
Swapping in your FCU takes just a few minutes with basic tools. Important detail: X-Series grip modules work only with magazines featuring the SIG mark on the baseplate, not the older "SIG SAUER" baseplates, so verify your magazine compatibility before ordering if you plan to use existing inventory.
X-Series grip modules only accept magazines with the SIG mark on the baseplate. If your magazines have "SIG SAUER" printed on the baseplate, they won't work with this module. You'll need to verify your magazine compatibility or switch to X-Series compatible magazines for reliable feeding.
You'll need a P320 firing control unit (the serialized part), plus a compatible 9mm, .40, or .357 SIG slide and barrel assembly. The grip module alone is just the frame. The extended magwell and internal grip weight are sold separately if you want those features.
Pull out the takedown lever on your current grip, lift the FCU and slide forward out of the old frame, then reverse the process to seat it into the X-Series module. The whole swap takes just a few minutes with no special tools required. Make sure you have the correct slide and barrel for your chosen caliber before assembly.
Yes. The small grip is noticeably slimmer, making it a better fit for people with smaller or medium hands. The X-Series overall design is thinner than standard P320 grip modules, so if you're moving from a medium to a small, expect a meaningful reduction in grip circumference. Many shooters appreciate this for better control without the bulk.
