In Stock: P322

You know the feeling. You’ve been tracking the Sig Sauer P322 for weeks, maybe months. Every forum thread mentions its 20+1 capacity, its optics-ready slide, its legendary trigger straight out of the box. You’ve seen the YouTube videos of guys running drills, the effortless follow-up shots, the grin that comes from a rimfire pistol that doesn’t feel like a compromise. But every time you click ‘add to cart,’ you’re met with a backorder notice or a price that’s crept into the stratosphere. That ends today. This isn’t just another listing; this is your notification. The P322 is in stock, priced to move, and sitting on our shelf in Boise, ready for its new home range.

Miamishooterssupply is a Boise, ID-based retailer specializing in firearms and components for the serious enthusiast. The Sig Sauer P322 is a 22 LR semi-automatic pistol built for high-volume training and unmatched modularity. Its defining feature is a 20+1 round capacity paired with a suppressor-ready, optics-ready platform that outclasses every other rimfire pistol in its class. We have the P322 in stock and ready to ship today for $373.11.

Let’s talk about what makes the P322 more than just a plinker. From an armorer’s perspective, Sig engineered this from the ground up to be a system, not just a pistol. The aluminum alloy slide is milled with a clean optics cut that accepts the Sig Romeo Zero Elite footprint directly—no clunky adapter plates. The barrel is threaded 1/2″-28, ready for your suppressor or compensator right out of the box. Internally, the trigger is the star. It’s a straight, skeletonized design with a clean break right around 3.5 pounds and a short, positive reset. For anyone coming from a centerfire Sig, the manual of arms is identical, making this the most cost-effective training tool you can own.

The modular grip frame is a masterstroke. It uses a serialized fire control unit, similar to the P320, allowing you to swap grip modules for different hand sizes or aesthetics. The included medium module fits most shooters, but small and large options are available. This isn’t just about comfort; it’s about building muscle memory on a platform that can scale with your needs. The magazines are another engineering win. They’re clear polymer, so you can see your round count at a glance, and they load easily to their full 20-round capacity—a rarity in the rimfire world where 10-round magazines are the norm.

Where the P322 Earns Its Keep

I’ve handled enough rimfire trainers to know the common pain points: finicky magazines, heavy triggers, and a ‘cheap’ feel. The P322 addresses each one. The magazine design, with its easy-loading follower and robust feed lips, is reliable with a wide range of ammunition. The trigger is a legitimate match-grade component you’d expect on a pistol costing twice as much. The build quality, from the slide serrations to the takedown lever, has the solidity of a centerfire Sig. This is the pistol you use to introduce new shooters, to drill fundamentals without breaking the bank on 9mm, and to simply have fun with a suppressor on a quiet afternoon. It bridges the gap between a toy and a tool perfectly.

Pros & Cons: The Straight Talk

✅ Pros:

• Unmatched Capacity: 20+1 rounds of .22 LR is a game-load for training sessions and competitions.
• Superior Trigger: The factory-installed trigger is exceptional, with a crisp break and tactile reset that accelerates skill development.
• Fully Outfitted Platform: Optics-ready cut and threaded barrel are standard, saving you $100+ in aftermarket work.
• Sig Sauer Ergonomics & Controls: If you run a P320 or P365, the manual of arms is identical, making for seamless transition training.
• Modular Grip System: The serialized FCU allows for easy grip module swaps to tailor fit and feel.
• Reliable Magazine Design: The clear, easy-loading 20-round magazines are consistently reliable with quality ammunition.

❌ Cons:

• Rimfire Ammo Sensitivity: Like all .22 LR pistols, it performs best with quality, high-velocity ammunition. Bulk pack sub-sonics may cause cycling issues. For a centerfire option with less ammo sensitivity, see our 9mm handguns.
• Magazine Cost: Additional magazines are a Sig-priced premium. It’s an investment in your training setup.
• Size: It’s a full-size pistol. If you’re looking for a compact .22 LR for concealed carry training, this isn’t it. Check our compact handguns for smaller platforms.

Who Should (and Shouldn’t) Buy the P322

Buy it if: You’re a Sig P320/P365 owner wanting a dedicated, low-cost training analog. You’re a competitive shooter looking for a rimfire division pistol that doesn’t hold you back. You’re an instructor or range owner needing a reliable, high-capacity .22 for teaching fundamentals. You’re a suppressor enthusiast wanting a host pistol that’s ready to go. You’re a tinkerer who appreciates a modular platform you can customize.

Skip it if: Your primary need is a ultra-compact .22 LR for backpacking or specific niche carry. You exclusively want the absolute cheapest .22 plinker available and aren’t concerned with performance or features. Your budget is strictly for a centerfire defensive pistol first and foremost.
