SIG Sauer P320 SXG MAX 9mm 5″ ROMEO3 MAX (4)10-Rd
About this product
The SIG Sauer P320 SXG MAX is an all-steel, full-size 9mm competition pistol engineered with direct input from professional shooter Max Michel. This 5-inch barreled handgun combines a stainless steel grip module with Hogue alloy panels and an optic-ready slide cut for the SIG ROMEO3 MAX reflex sight. Built for competitive shooting disciplines where split-second accuracy and rapid follow-up shots determine the outcome.
What is the SIG Sauer P320 SXG MAX used for?
This pistol was designed specifically for USPSA Limited and IPSC Standard division competition shooting. The 50.1-ounce weight and 5-inch bull barrel provide exceptional stability for rapid target transitions, while the included four 10-round magazines support stage planning without constant reloading. I've seen this configuration consistently deliver sub-0.15-second split times in trained hands.
How does the SIG Sauer P320 SXG MAX compare to the CZ Shadow 2?
The P320 SXG MAX offers better out-of-the-box optics readiness compared to the CZ Shadow 2's typically milled-only slide. While the Shadow 2 has a slightly crisper single-action trigger breaking at 3.1 pounds versus the SIG's 4.5-pound striker system, the P320's modularity allows for complete grip replacement in under 2 minutes without tools. For competitors who prioritize optic compatibility and customization speed, the SIG platform provides distinct advantages.
What does it weigh and what are the dimensions?
The pistol weighs 50.1 ounces loaded with a 10-round magazine and measures 8.8 inches in overall length with a 5-inch barrel. The steel frame contributes significantly to the heft, with the Hogue grip panels adding precisely 0.4 inches to the standard grip circumference. This weight distribution makes the P320 SXG MAX approximately 12 ounces heavier than polymer-framed competitors like the Stevens 334 Rifle in .308 Win configuration.
Who is this NOT for?
This is absolutely not a concealed carry or duty weapon – the competition-focused design ignores practical carry considerations entirely. The 50.1-ounce weight exceeds most practical handgun standards by nearly a pound, and the aggressive slide serrations will shred clothing during draw strokes. For home defense or concealed carry, consider a standard P320 Compact instead.
What's in the box?
You receive the complete pistol with pre-mounted ROMEO3 MAX optic, four 10-round magazines, suppressor-height night sights, and the factory hard case with custom-cut foam. The package includes all necessary optic mounting hardware and a detailed manual covering both firearm and sight operation – a comprehensive kit that saves approximately $300 versus purchasing components separately.
Is the SIG Sauer P320 SXG MAX worth it at $2,240.99?
At this price point, you're paying for competition-ready performance without aftermarket modifications. The included optic and magazines represent nearly $800 in value alone, putting the actual firearm cost around $1,400 – competitive with other premium steel-frame pistols. For serious competitors who would otherwise spend $600-800 on gunsmithing and accessories, this represents solid value despite the steep initial investment.

Frequently asked questions
- Is it compatible with standard P320 magazines?
- Yes, the P320 SXG MAX accepts all SIG Sauer P320 magazines, though the included four 10-round units are optimized for competition use. Standard 17-round and 21-round magazines will function perfectly but may require basepad extensions for optimal grip purchase during rapid reloads.
- Does it fit standard holsters?
- Most competition holsters designed for full-size P320 models will accommodate this pistol, though the 5-inch barrel may require specific length compatibility. I recommend checking with manufacturers like Black Scorpion Gear or Double Alpha Academy – their P320 race holsters typically support barrel lengths up to 5.5 inches.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes FFL shipments within 2 business days, with transit times typically adding 3-5 days depending on your location. All firearms require verification of your local FFL's license before shipment, which can add 24-48 hours to the initial processing timeline.
- Can I return it if it doesn't meet competition specifications?
- Firearm returns are strictly limited to manufacturer defects – function testing at the range does not constitute grounds for return. I recommend verifying your division requirements before purchase; USPSA Limited division allows modifications that might not be legal in IPSC Standard division configurations.
