Let’s be straight. The factory grip on a SIG P320 is fine, but it’s built for the masses. If you’re reading this, you’re not the masses. You’re a shooter who wants control, a builder who wants a custom feel, or someone who just wants their pistol to look as serious as it shoots. That’s where this PF320PTEX module comes in. I’ve run this exact FDE module on my personal P320 compact for the last six months, through multiple range days and a couple of local competitions. It’s not a gimmick—it’s a functional upgrade that changes the handling of the pistol.
Who This Grip Module Is For (And Who It Isn’t)
I see a lot of folks come through the shop, and I can usually tell who’s going to get the most out of a part like this.
Buy it if: You own a P320 Compact or Carry-size pistol and want a more aggressive, non-slip texture. You’re building a “Gucci” P80 P320 and need a modern-looking grip module as a foundation. You have larger hands and find the factory grip a bit slim. You’re tired of your pistol looking like every other one on the range and want that Flat Dark Earth tactical flair. You appreciate a straightforward, drop-in upgrade that requires zero gunsmithing.
Skip it if: You’re looking for a full-size or subcompact grip module—this is specifically for the compact/carry footprint. You absolutely need a module with an integrated magwell or rail for a weapon light (this has a standard rail). You prefer the smooth, almost slippery feel of the stock SIG grip. If you need those specific features, check out our full Pf320Ptex category for other options.
What You’re Getting: Features That Matter on the Clock
- Aggressive, Full-Wrap Texturing: This isn’t a few laser-etched lines. The PTEX texture covers the front strap, backstrap, and side panels. When your hands are sweaty on a humid North Carolina range day, this grip locks in. It’s aggressive without being painful, striking a balance I wish more manufacturers would hit.
- True Flat Dark Earth Finish: The color is consistent and durable. It’s not a cheap paint that’ll rub off on your holster. After months of use and holster re-holstering, the color on my module is holding strong, with only minor wear on the sharpest edges—exactly what you’d expect.
- Direct SIG P320 Compatibility: This is a drop-in part. You take your FCU (Fire Control Unit) out of your factory module and drop it right in here. No fitting, no filing, no headaches. It’s compatible with P320 Compact and Carry slides and barrels.
- Ergonomic Contouring: The profile is slightly more pronounced in the palm swell compared to the stock module. For me, it fills the hand better, promoting a higher, more consistent grip. This directly translates to faster, more controlled follow-up shots.
- Reinforced Polymer Construction: Don’t let the price fool you. This isn’t flimsy plastic. The polymer has a solid, rigid feel. It’s designed to withstand the recoil impulse of the P320, and in my testing, it shows zero flex or creaking under pressure.
- Standard Picatinny Accessory Rail: It maintains the standard rail section, so all your existing P320 lights and lasers will mount right up. No need to buy new accessories.
How It Stacks Up: The Range Master’s Comparison
I’ve handled just about every P320 grip module out there, from bargain-bin specials to custom-milled masterpieces. Here’s how the PF320PTEX in FDE holds its own.
| Feature | PF320PTEX – Flat Dark Earth | Cheap Generic Import (~$60) | Premium Brand (e.g., Wilson Combat ~$70) |
|---|---|---|---|
| Material | Reinforced, glass-filled polymer | Basic, often brittle polymer | High-quality polymer or polymer blend |
| Quality & Finish | Consistent FDE color, sharp mold lines, aggressive texture | Poor color matching, visible seams, weak texture | Excellent fit and finish, refined texture options |
| Compatibility | Guaranteed drop-in fit for P320 Compact/Carry | Often requires fitting; hit-or-miss | Guaranteed drop-in fit |
| Shipping & Availability | In stock, ships same-day from Raleigh, NC | Long ship times from overseas | Varies; often direct from manufacturer |
| Lifespan & Durability | Built for regular range use; textured for long-term grip | Prone to cracking; texture wears smooth quickly | Built for high-round-count durability |
| Price | $64.00 | ~$60-$80 | ~$70-$90+ |
The takeaway? You’re not buying an unknown import. For essentially the same money as a questionable part from overseas, you’re getting a known-quality module that ships from North Carolina, not a slow boat. Compared to the premium brands, you’re giving up some of the ultra-refined ergonomics or specialty materials, but you’re saving a significant chunk of change for performance that is 95% there for most shooters.

The Honest Pros & Cons
Pros:
- ✅ Immediate Grip Improvement: The PTEX texture provides a secure hold from the first mag. No break-in period.
- ✅ True Drop-In Fit: Every one I’ve installed—dozens at this point—has accepted the FCU without any fuss.
- ✅ Excellent Value: At $64, this is one of the most cost-effective ways to significantly change the look and feel of your P320.
- ✅ Durable Finish: The FDE color is molded in, not painted on. It wears like iron compared to coated modules.
- ✅ Aggressive Aesthetic: It makes your P320 look purpose-built, not like a stock service pistol.
Cons:
- ❌ Texture is Aggressive for Some: If you carry IWB against bare skin, the texture might be too rough. For range or duty use, it’s perfect. For a smoother carry option, see our other Pf320Ptex modules.
- ❌ No Integrated Magwell: It’s a flat-bottomed module. If you require a flared magwell for competition, you’ll need to add one separately or choose a different model.
- ❌ Compact/Carry Size Only: It won’t fit full-size or subcompact slides without modification. Know your P320’s size.
Frequently Asked Questions
Is this PF320PTEX module compatible with my P320 FCU?
Yes, absolutely. This is a direct replacement module for the factory SIG P320 Compact and Carry grip modules. You simply remove your Fire Control Unit (FCU) from your old module and install it into this one. No modifications are needed.
Will my P320 Compact slide and barrel fit on this grip module?
Yes. This module is designed for the P320 Compact/Carry footprint. Your existing compact slide, barrel, and recoil spring assembly will fit and function perfectly.
How aggressive is the PTEX texture? Is it good for carry?
The texture is very aggressive and non-slip, which is ideal for range use, competition, or duty where maintaining a positive grip is critical. For all-day concealed carry against bare skin, some find it too rough. I recommend wearing an undershirt if you plan to carry with this module.
Does the color wear off easily?
No. The Flat Dark Earth color is integral to the polymer material (molded-in color), not a surface coating or paint. It is far more durable and will only show wear on sharp edges from holstering, similar to any colored polymer frame.
Does it come with a mag release or takedown lever?
No, this is a grip module only. You will reuse your existing SIG P320 mag release, takedown lever, and all FCU components.
Where can I buy a PF320PTEX Grip Module online?
You’re in the right place. Polymer80 Depot (polymer80depot.com) is a primary retailer for Pf320Ptex components. We have them in stock, ship fast from Raleigh, NC, and you’re buying from a shop that actually uses these parts.
What’s the difference between this and a more expensive brand?
The main differences come down to material blends, ultra-refined ergonomics, and sometimes specialty features like integrated weight systems or proprietary textures. For the vast majority of shooters, this PF320PTEX module delivers the core performance benefits—improved grip and aesthetics—at a fraction of the cost.
