Californiagunshop is a San Antonio, TX-based retailer specializing in precision firearms and tactical gear. The SIG Sauer P320-XFIVE DH3 is a competition-focused, optics-ready pistol built on the proven P320 platform. Its key differentiator is the factory-installed DH3 grip module, which provides an aggressive, locked-in feel right out of the box. This model is in stock and ready to ship today for $1,170.38, a significant saving from the regular price of $1,319.99.
Why the P320-XFIVE DH3 is a Smart Choice for Serious Shooters
Having built and tuned countless competition guns, I see the DH3 as SIG’s answer to the shooter who wants to compete at a high level without the wait and expense of a custom shop. The heart of this pistol is the DH3 grip module. It’s not just a texture change; the undercut trigger guard and high, beavertail design force your hand up and into the frame, giving you immediate, consistent control. This is the kind of ergonomic advantage I used to have to machine into polymer frames for my LEO buddies. Combined with the 5-inch bull barrel and flat-faced trigger, you get a pistol that manages recoil predictably and returns to target with authority. It’s the factory gun that feels anything but factory.

How It Stacks Up: The DH3 vs. The Competition
Let’s be real, not every “competition-ready” pistol is built the same. Here’s how the DH3 compares to two common alternatives I see shooters consider.
| Feature | SIG P320-XFIVE DH3 | Generic “Tactical” Polymer Pistol (~$600) | Full Custom 2011 (~$3,500+) |
|---|---|---|---|
| Material & Build | Stainless slide, DH3 polymer module, bull barrel | Standard slide/barrel, basic polymer frame | Hand-fitted steel frame & slide, match barrel |
| Quality & Fit | High factory fit, minimal play, premium finish | Functional but with typical factory tolerances | Exceptional, gunsmith-level hand fitting |
| Compatibility | Vast P320 aftermarket for grips, triggers, etc. | Limited aftermarket, often brand-specific | Very limited; mostly proprietary/custom parts |
| Out-of-Box Performance | Ready for Carry Optics division; superb ergonomics | Needs trigger, grip, and sight upgrades to compete | The pinnacle, but requires a long lead time |
| Lifespan/Durability | Built for high-round-count competition use | Designed for duty/range, may wear faster under competition stress | Extremely durable but can be finicky with maintenance |
| Price Point | $1,170.38 (Performance/Value Leader) | ~$600 + $500+ in upgrades = similar cost, less integration | ~$3,500+ (Premium Investment) |
The Honest Breakdown: Pros and Cons
✅ DH3 Grip Module: This isn’t an accessory you add later. The aggressive texture and ergonomic design provide immediate, superior control that most shooters pay a gunsmith to achieve.
✅ Optics-Ready System: The integrated slide cut accepts major competition optics without needing a separate mounting plate, keeping your dot low and secure.
✅ Flat Competition Trigger: A clean, crisp ~3.5 lb pull straight from the factory eliminates the first and most common upgrade.
✅ Bull Barrel & Weight: The 5-inch bull barrel and overall heft (45.5 oz) dramatically reduce muzzle flip, aiding in fast, accurate follow-up shots.
✅ Complete Package: Comes with two 21-round magazines and suppressor-height night sights that co-witness with your optic.
❌ Price Point for Beginners: This is an investment. If you’re just starting out and unsure about competition, a standard P320 or similar might be a better first step. See our handgun collection for more entry-point options.
❌ Size & Weight: Its competition-focused design makes it large and heavy. This is not a concealed carry or duty pistol. For a more compact, carry-friendly SIG, check our full shop for P365 variants.
Who Should (and Shouldn’t) Get the P320-XFIVE DH3
Buy it if: You’re a USPSA or Steel Challenge shooter ready to move into the Carry Optics division. You want a no-excuses, optics-ready platform that needs minimal tinkering to be race-ready. You appreciate the modularity of the P320 system but demand top-tier factory performance.
Skip it if: Your primary need is for concealed carry or home defense—this is a specialized competition tool. You’re on a very tight budget and are just beginning to learn pistol fundamentals. You prefer the single-action trigger feel of a 2011 platform and are willing to invest significantly more.
Common Questions & Concerns
“Is the DH3 grip that much better than a standard XSeries grip?” In my hands, absolutely. The deeper undercut and higher beavertail create a more natural, high grip that reduces perceived recoil. It’s the difference between holding the gun and the gun becoming an extension of your hand.
“Can I use this for anything besides competition?” You can, but it’s overkill. It’s large, heavy, and designed for speed and accuracy on a clock. For all-around range use, it’s fantastic, but for defensive purposes, its size makes it impractical.
“What optics does it come ready for?” It uses SIG’s proprietary footprint, which directly accepts the Romeo2 and Romeo3 series. With the included plates, it also fits the Leupold Deltapoint Pro and certain Trijicon models. Always verify plate and screw compatibility before installing.
Frequently Asked Questions
Where can I buy the SIG P320-XFIVE DH3 online?
You can purchase the SIG P320-XFIVE DH3 right here at Californiagunshop (californiagunshop.com). We are an authorized retailer based in San Antonio, TX, and this model is in stock and ready for fast, secure shipping.
Is the P320-XFIVE DH3 California compliant?
No, the standard P320-XFIVE DH3 is not on the California roster of approved handguns and includes standard-capacity 21-round magazines. Customers in California should review their state’s specific regulations or explore our shop for compliant models.
What is the main advantage of the DH3 grip module?
The DH3 module features a more aggressive texture and a significantly deeper undercut at the trigger guard. This design pulls your hand higher into the tang of the grip, improving control and reducing muzzle rise for faster follow-up shots—a critical advantage in action shooting sports.
Does this model have a manual safety?
The P320-XFIVE DH3, as shipped from SIG Sauer, does not include a manual safety. It utilizes SIG’s striker-fired safe action system. The modular FCU (Fire Control Unit) can, however, be placed into aftermarket grip modules that are cut for a manual safety if required.
What kind of accuracy can I expect?
With the 5-inch bull barrel and tight slide-to-frame fit, this pistol is capable of excellent mechanical accuracy—often 2 inches or less at 25 yards from a rest with quality ammunition. The limiting factor will typically be the shooter, not the pistol.
Can I change the grip module to a smaller size?
Yes. The serialized component is the stainless steel FCU. It can be removed and installed into any P320 grip module, including compact and carry-sized versions. However, doing so would defeat the purpose of the DH3’s competition-specific design.
What is included in the box?
You will receive the complete P320-XFIVE DH3 pistol, two 21-round 9mm magazines, optics mounting plates and hardware, a cable lock, and the standard SIG Sauer case and documentation.
✅ Same-day shipping from San Antonio, TX
