Wilson Combat WCP320 Carry Action Tuned Curved Trigger Green
Wilson Combat WCP320 Carry Action Tuned Curved Trigger Green
This robust, fast-handling pistol wears our Wilson Combat-engineered polymer Carry-2 grip module with a 3-slot rail. This newly designed and manufactured grip has enhanced traction, smoother reloading, improved pointablity, and superb recoil control in dynamic shooting.
The Wilson Combat WCP320 Carry, Action Tuned, Curved Trigger, Green Module is a customized SIG Sauer P320 Carry in 9mm, built around Wilson Combat’s upgraded grip module, X-TAC-machined slide, sights, and an optional Action Tune using Grayguns components. The green version uses the same Carry grip geometry as the other color variants.

Action-Tuned curved trigger
This is the part that makes your configuration more specialized than the standard WCP320 Carry.
Wilson Combat offered the WCP320 Carry with either the standard SIG XFULL trigger or an Action Tune performed by Wilson Combat gunsmiths. The Action Tune uses Grayguns custom trigger components, and the upgraded version could be ordered with either a flat or traditional curved trigger.
So the description:
Action Tuned, Curved Trigger
means this isn’t simply a standard P320 Carry with a curved trigger shoe. It identifies the upgraded Wilson Combat/Grayguns trigger configuration.
I wouldn’t assign a specific trigger-pull weight to an individual example without measuring that particular pistol.
Green Wilson Combat grip module
The green module is an actual factory-listed color for Wilson Combat’s WCP320 Carry grip module. Wilson lists black, gray, green and tan color choices.
The Carry module weighs approximately 3.2 oz. and measures approximately:
-
Length: 7¼”
-
Height: 4¼”
-
Grip front-to-back: approximately 2″
Grip design
The Wilson module substantially changes how the P320 feels in the hand. It incorporates:
-
Modified backstrap
-
Undercut frontstrap
-
Radiused/reshaped trigger guard
-
Wilson Combat Starburst side texture
-
More aggressive front/backstrap texturing
-
Flared magazine-well area
-
Internal slots for rod-style tungsten weights
Wilson says the module includes the factory SIG magazine release, spring and lock and is compatible with standard holsters.
The grip is available with either manual-safety or no-manual-safety configuration, so the green color by itself doesn’t tell you which safety configuration a particular pistol has.
Slide
The WCP320 Carry uses a Wilson Combat-machined X-TAC slide.
The X-TAC pattern appears on:
-
Front cocking serrations
-
Rear cocking serrations
-
Slide top
-
Other machined portions of the slide
The machining isn’t merely cosmetic; it provides additional serrated surfaces for manipulating the slide.
The slide and barrel receive a black DLC (Diamond-Like Carbon) finish, with Wilson describing the finish as incorporating chromium and tungsten underlayers for durability and corrosion/abrasion resistance.
Sights
The standard WCP320 Carry setup uses:
-
Wilson Combat Battlesight rear
-
Red fiber-optic front
The Battlesight is Wilson Combat’s rugged rear-sight design, while the fiber-optic front provides a highly visible aiming reference.
Barrel
The Carry version uses a 3.9-inch chromoly barrel.
The combination of the 3.9″ barrel and full-size Carry grip is what gives the WCP320 Carry its characteristic configuration: a relatively compact slide/barrel with a full-capacity grip.
Magazine capacity
The published configuration uses:
17-round 9mm magazines
The original WCP320 Carry specification lists two 17-round X-Series magazines.
Magazine configuration can of course vary according to the specific package and jurisdiction.
Carry vs. Full-Size WCP320
This distinction matters because Wilson also sells a full-size WCP320.
| WCP320 Carry | WCP320 Full Size | |
|---|---|---|
| Barrel | 3.9″ | 4.7″ |
| Overall length | 7.5″ | 8.25″ |
| Weight | 26.8 oz. | 29.2 oz. |
| Capacity | 17 rd | 17 rd |
| Grip | Carry | Full Size |
The full-size specifications are documented separately by Wilson Combat’s coverage of the WCP320.
Green vs. tan
The green module doesn’t change the mechanical specifications of the pistol. It is primarily a grip-module color choice.
Wilson does note that polymer color can vary somewhat between production batches, so the actual green can differ subtly from product photography.
Tungsten-weight option
One interesting feature of the Wilson grip is the provision for rod-style tungsten weights.
These can add weight inside the grip and alter the pistol’s balance. Wilson specifically says its WCP320 module uses rod-style weights and is not compatible with the X-Five tungsten weights
Compatibility
The Wilson Carry module is designed for the P320 Carry configuration and supports 9mm, .40 S&W and .357 SIG module compatibility according to Wilson’s published information.
One important limitation: Wilson explicitly says its SIG P320 grip modules are not compatible with California-compliant P320 versions.
Historical pricing
A contemporary review lists the WCP320 Carry at an MSRP of approximately $1,195 in the tested configuration. That’s historical MSRP rather than a current-market valuation.
What makes your particular configuration distinctive
Putting the description together:
Wilson Combat WCP320 Carry
→ 9mm
→ 3.9″ barrel
→ 7.5″ overall length
→ 17-round configuration
→ X-TAC-machined slide
→ black DLC finish
→ Battlesight rear/red fiber-optic front
→ Action-Tuned trigger
→ traditional curved trigger
→ green Wilson Combat Carry grip module
The Action Tune + curved trigger + green module combination is therefore a specific upgraded WCP320 configuration, rather than simply a standard P320 with a Wilson grip.
