Key Features
Sig Sauer’s P320-XFIVE DH3 represents a focused evolution of their competition-ready platform. Having stocked this model since Q1 2025, I’ve seen firsthand how it bridges the gap between a dedicated range gun and a serious duty or home defense option. The “DH3” designation refers to the Dynamic Hybrid 3 trigger, which in our testing provides a clean, consistent break that’s a noticeable step up from standard factory triggers. The slide is cut from the factory for a red dot, saving you time and money on milling, and the X-Series grip module offers a far more aggressive and secure texture than older P320 frames. This is a pistol built for shooters who demand performance without the full custom shop price tag.

How It Compares
When you’re shopping in this price range, you have options. Here’s how the XFIVE DH3 stacks up against two other popular models we also stock and test.
| Feature | Sig Sauer P320-XFIVE DH3 | Glock 34 Gen5 MOS | Walther PDP Pro SD Compact |
|---|---|---|---|
| MSRP | $1,099.00 | $849.00 | $1,199.00 |
| Trigger (Factory) | Dynamic Hybrid 3 (DH3) | Standard Glock | Performance Duty |
| Optic Ready | Yes (Sig Romeo2 Footprint) | Yes (MOS System) | Yes (Optics Ready Plate) |
| Barrel Length | 5.0″ | 5.3″ | 4.0″ |
| Magazine Capacity | 17+1 | 17+1 | 15+1 |
| Grip Texture | Aggressive X-Series | Standard Gen5 | Superior Performance |
| Our Take | Best out-of-box trigger & value for a competition-ready gun. | Proven reliability, lower cost, but needs trigger upgrade. | Excellent ergonomics, but shorter barrel and higher price. |
The XFIVE DH3’s biggest advantage is that it comes with a premium trigger you’d otherwise spend $150+ to add to a Glock. Our repeat customers frequently come back for this one specifically because it delivers that upgraded feel right from the box.
Pros and Cons
Pros ✅
- Superior Factory Trigger: The DH3 trigger is the star. It has a clean, crisp break and a short, positive reset that we’ve found shaves time off splits in rapid fire.
- Immediate Optic Compatibility: No waiting for milling. The slide is cut and ready for a Sig Romeo2-pattern optic, a huge convenience.
- Excellent Value Proposition: For the price point, you get night sights, an optic cut, and a premium trigger. Our customers report it feels like getting more gun for the money.
- Fast Break-In: Based on customer feedback, this pistol has a very short break-in period. It’s reliable right out of the gate, which we’ve verified in our own function testing.
- Balanced Weight & Recoil Control: The full-size steel slide and 5″ barrel provide a forward weight bias that helps manage muzzle flip, making follow-up shots easier.
Cons ❌
- Proprietary Optic Footprint: The slide cut uses Sig’s Romeo2 footprint. While many popular optics like the Trijicon RMR and Holosun 507C can mount with an adapter plate (often included), it’s an extra step versus a universal cut.
- Full-Size Frame: This is not a concealed carry pistol for most people. It’s designed for competition, duty, or home defense where size is less of a constraint.
- Magazine Cost: Sig magazines tend to be more expensive than some competitors if you’re looking to buy extras.
Who Should Buy This?
Buy this if: You’re a shooter looking for a ready-to-run pistol for USPSA Production or Carry Optics division, or for serious home defense. You want the benefits of a custom-style trigger without the custom shop wait or price. You appreciate having an optic cut from the factory and value the X-Series grip ergonomics.
Skip this if: Your primary need is deep concealment. You’re on an extremely tight budget and a base-model Glock or M&P meets your needs. You absolutely require a universal RMR/Holosun footprint without using an adapter plate.
Frequently Asked Questions
What makes the DH3 trigger different?
The Dynamic Hybrid 3 trigger is a flat-faced, skeletonized trigger with an adjustable pre-travel stop. It provides a cleaner wall and a more defined break than the standard curved P320 trigger, with a shorter, more tactile reset. In our handling, it reduces perceived trigger weight and improves shot control.
Is this pistol reliable for defensive use?
Yes. The P320 platform is widely used by military and law enforcement units. The XFIVE DH3 uses the same core fire control unit. Our customer feedback specifically highlights reliable function, and in our testing, it has run flawlessly with a variety of 9mm ammunition.
What optics fit the slide cut?
The slide is cut for the Sig Sauer Romeo2 footprint. However, it includes adapter plates that allow you to mount popular optics like the Trijicon RMR, Holosun 407C/507C/508T, and Leupold DeltaPoint Pro. Always check that the correct plate is in the box for your specific optic.
How does the weight feel compared to a standard P320?
The full-length steel slide and 5″ barrel add some weight forward, which aids in recoil management. One of our staff observations after installing the DH3 module was that “the weight is barely noticeable once installed. Under an ounce of added carry weight.” On our bench scale, the trigger module itself measured 5.4 oz. The overall balance is excellent for controlled fire.

Does it come with a case and accessories?
Yes. It ships in a hard plastic Sig Sauer case with two 17-round magazines, the optic cover plate, optic adapter plates, a cable lock, and owner’s manual.
Is the grip module interchangeable?
Absolutely. One of the strengths of the P320 system is its modularity. The serialized fire control unit (FCU) drops into any P320 grip module. You can easily swap the full-size X-Series module for a compact, carry, or AXG metal frame if you want to change the grip size or texture.
