SIG SAUER P320 XCarry 9mm 3.9in XRAY3 2x10rd Mags
Pros & cons
What works
- Weighs 28.5 oz unloaded — 3.2 oz lighter than a Glock 19 Gen5 MOS with comparable dimensions.
- Optic-ready RMSc footprint milled directly into slide — eliminates need for aftermarket milling ($150-200 value).
- XRAY3 front sight provides high-visibility green ring in daylight and tritium glow for 12+ years.
- Modular FCU allows grip swaps in under 90 seconds without FFL paperwork — unlimited ergonomic customization.
Trade-offs
- No optic plate included — requires direct-mount optic or separate $45-70 adapter plate.
- 10-round magazines only — free-state buyers must invest $90-110 for two 17-round replacements.
- Factory grip texture is moderate — aggressive shooters may add Talon Grips or stippling ($20-80).
- Black nitride slide finish shows carbon buildup quickly — requires routine cleaning after 200-300 rounds.

About this product
What is the SIG SAUER P320 XCarry 9mm pistol? It’s a compact, modular, striker-fired handgun chambered in 9mm Luger, designed around SIG’s M17/M18 military-proven P320 fire control unit and optimized for concealed carry with an optic-ready slide and XRAY3 day/night sights. I evaluate this configuration for its balance of shootability and daily concealment, a task that demands specific dimensions and reliable controls. Its 3.9-inch barrel and 7.4-inch overall length place it squarely in the compact category, distinct from micro-compacts or full-sized duty guns, offering a versatile middle ground.
What is the SIG SAUER P320 XCarry used for?
The P320 XCarry is designed primarily as a concealed carry pistol, balancing shootable dimensions with accessory readiness. Its 3.9-inch barrel and 1.3-inch slide width provide sufficient sight radius and muzzle velocity for defensive accuracy without printing excessively under a cover garment. The optic-ready slide and modular grip system allow for rapid personalization—you can swap the grip module in under 90 seconds—making it suitable for shooters who want a single, adaptable platform for carry, competition, or home defense without investing in multiple complete firearms.
How does the SIG SAUER P320 XCarry compare to the Ironclad Armory Stevens 334 Rifle?
The P320 XCarry and the Stevens 334 Rifle serve entirely different roles; the XCarry is a compact defensive handgun, while the Stevens 334 is a bolt-action hunting rifle. The XCarry is better for personal defense in close quarters due to its semi-automatic action and 10+1 capacity, offering rapid follow-up shots, whereas the Stevens 334 in .308 Win is superior for precise, ethical hunting at distances beyond 100 yards. Comparing them highlights that tool selection is mission-critical—one is for concealment and fast handling, the other is for deliberate, ranged shots.
What does it weigh and what are the dimensions?
Unloaded with an empty magazine, the P320 XCarry weighs 28.5 ounces (808 grams), and its overall dimensions are 7.4 inches long, 5.5 inches high (with magazine inserted), and 1.3 inches wide. The barrel length is precisely 3.9 inches, providing a legal minimum for some suppressor host configurations while keeping the slide manageable for concealed carry. These numbers matter: the 28.5-ounce weight, while not a featherweight polymer micro-compact, provides enough mass to mitigate felt recoil, improving controllability for rapid strings of fire during qualification drills.
Who is this NOT for?
This pistol is not for first-time shooters seeking a simplistic, low-maintenance firearm, nor is it for those requiring maximum magazine capacity in restrictive jurisdictions. The modularity and accessory rails invite additional costs—optics, lights, and grip modules—which can double the initial investment. If your priority is a dedicated, high-capacity range toy without concern for concealment, a full-sized model like the P320 X-Full would be a better fit, offering a longer sight radius and higher magazine capacity for purely recreational shooting.
What's in the box?
Inside the factory case, you receive the pistol with the installed XRAY3 front sight and contrasting rear sight, two 10-round flush-fit magazines, a cable lock, and the owner's manual. Notably, SIG does not include an optics mounting plate—the RMSc footprint is milled directly into the slide, requiring direct-mount micro optics or a proprietary adapter plate purchased separately. This is a critical detail; if you plan to mount a Holosun 507K, for example, you'll need to verify direct compatibility or source the correct plate, adding $40-70 to your total cost.
Is the SIG SAUER P320 XCarry worth it at $744.99?
At $744.99, the XCarry is competitively priced against other optic-ready compact pistols like the Glock 19 MOS, offering superior out-of-the-box trigger and sights from a military-proven platform. You're paying for SIG’s engineering in the fire control unit, which is the serialized component, allowing legal grip module swaps without an FFL transfer—a feature many competitors lack. For a shooter who values modularity and plans to customize, this represents a solid foundation investment, akin to choosing a Stevens 555 Sporting O/U for its reliable, no-frills action over more ornate, expensive shotguns.

Frequently asked questions
- Is the optics cut compatible with a Holosun 507K?
- Yes, the slide's RMSc footprint is directly compatible with the Holosun 507K, allowing direct mounting without an adapter plate. Ensure you use the provided screws from Holosun, as SIG's factory screws may be too long and interfere with the extractor mechanism. Torque the mounting screws to 12-15 in/lbs to avoid shearing or stripping the threads during recoil.
- Does this pistol fit standard P320 holsters?
- The XCarry fits holsters designed for the P320 Compact or Carry models with a 3.9-inch barrel, but not holsters for the Subcompact or Full-sized frames. The slide width of 1.3 inches is consistent, but verify compatibility with your specific holster manufacturer—I recommend checking with Tier 1 Concealed or Black Point Tactical for molded options. Allow for a 1-2 week lead time if ordering a custom kydex rig.
- How long does shipping to an FFL typically take?
- Ironclad Armory processes and ships firearms within 3 business days of cleared payment, with transit times of 2-5 business days via FedEx or UPS. The total timeline from order to your FFL receiving the pistol is typically 5-8 business days, barring carrier delays or compliance verification. You must contact your chosen FFL beforehand to ensure they accept shipments and provide their current license.
- Can I swap the grip module for a Wilson Combat version?
- Absolutely—the serialized fire control unit drops directly into any P320 grip module, including Wilson Combat's Carry or Compact sizes, without an FFL transfer. The swap requires no tools and takes under two minutes; simply depress the takedown lever, slide the FCU out, and reverse the process. Wilson’s modules typically add $65-80 to your build but enhance ergonomics and texturing immediately.
- Does this work with a Streamlight TLR-7A weapon light?
- Yes, the integrated Picatinny rail section accepts the Streamlight TLR-7A perfectly, providing a flush fit with the 3.9-inch slide. The light adds 3.1 ounces to the front end, slightly altering the balance but not impeding holster fit in light-bearing models. I recommend using the provided rail key #4 for the most secure lockup during sustained fire.
- Are the magazines restricted to 10 rounds only?
- These included magazines are 10-round capacity, compliant with state restrictions, but the P320 platform accepts standard 15, 17, or 21-round SIG factory magazines. If you reside in a free state, you can purchase higher-capacity magazines separately; expect to pay $45-55 per 17-round mag. Always verify your local laws—possession of non-compliant magazines can carry felony charges in certain jurisdictions.
