Sig Sauer GRIPX5F943MBLK P320 Grip Module X-Five, 9mm Luger/40 S&W/357 Sig, Black Polymer, Medium Grip Size, Flared Magwell, Fits Full Size Sig P320

The Sig Sauer P320 Grip Module X-Five is a factory grip upgrade designed for shooters ready to dial in their full-size P320 pistol. If you run a P320 in 9mm Luger, .40 S&W, or .357 Sig and want to improve control and consistency, this medium-grip module engineers a higher grip angle and extended beavertail that work together to raise your hand position on the frame. That translates to less felt recoil and a more natural sight picture—especially valuable on the range or in competition where every shot counts.

The X-Five geometry includes a deeper undercut ahead of the trigger guard, giving your grip hand more real estate and a higher, more secure purchase. The flared magwell speeds up reloads by funneling rounds into the magazine reliably and fast. Inside the box you'll find a removable grip weight to fine-tune balance and a removable magazine funnel—both handy for dialing in the exact feel you want without permanent modification.

Installation is straightforward: the P320's modular design means swapping grip modules is a field-strippable operation. This black polymer module is medium-sized, so it fits hands that prefer something between compact and large. One compatibility note worth knowing: this module works with SIG Mark baseplates on magazines, but not with the older "SIG SAUER" text baseplates, so check your mag setup before ordering.

Frequently Asked Questions

Will this X-Five grip module work with my P320 full-size?

Yes—this module is engineered for full-size P320 frames and accepts fire control groups in 9mm Luger, .40 S&W, and .357 Sig. Because the P320 uses a modular design, you can swap grip modules without gunsmithing.

What magazines are compatible with this grip module?

This module works with magazines that have the SIG Mark on the baseplate. It is not compatible with magazines marked "SIG SAUER" on the baseplate, so verify your magazine baseplates before purchase.

What's included in the box?

The grip module comes with a removable grip weight for balance adjustment and a removable magazine funnel to help you load faster and more reliably.

How does the higher grip angle help my shooting?

The raised grip angle and extended beavertail position your hand higher on the frame, reducing muzzle flip and felt recoil. This naturally improves control and sight picture recovery, especially useful for range work, competition, or defensive shooting.
