Sig Sauer P322: High-Capacity .22LR with ROMEOZero Elite

When you’re evaluating a modern .22LR pistol for training, range time, and light defensive work, you want something that blends quality, capacity, and thoughtful engineering. We took a close look at a new contender that brings big features to small-bore performance while keeping controls intuitive for both hands.

SIG SAUER P322 delivers a factory-built package from New Hampshire with premium components and a focus on versatility.

The P322 was completely designed and built by SIG SAUER in New Hampshire and arrives with features you usually see only on higher-priced competition pistols. It ships with a ROMEOZero Elite installed at the factory, a suppressor-ready threaded barrel adapter, ambidextrous controls, interchangeable flat and curved triggers, and a fiber optic front sight paired with that ROMEOZero Elite optic. At $549.99, it positions itself as the highest-capacity, most advanced .22 pistol in its class while remaining competitively priced. Shop this product

Design & build: American craftsmanship that matters

Built end-to-end in New Hampshire, the SIG SAUER P322 reflects the kind of attention to tolerances and ergonomics SIG is known for. The frame and slide geometry favor natural pointability, and the ambidextrous controls mean left- and right-handed shooters get the same level of access to slide stop and magazine release. For shooters who transition between hand orientations or train with both hands, that’s a practical advantage.

Factory optic & sighting options

This model ships from the factory with a ROMEOZero Elite red dot optic installed, giving you a crisp 3 MOA aiming point right out of the box. SIG paired the optic with a fiber optic front sight for quick co-witnessing and failover in varied light. For a small-bore pistol focused on fast, accurate follow-up shots, that combination reduces the time between acquiring and engaging a target at common range distances.

Key features explained

Don’t get distracted by marketing shorthand — these features have practical implications on the range and in training:

Threaded barrel adapter — suppressor-ready from day one

The threaded barrel adapter provides an easy path to sound suppression and muzzle accessory upgrades. For training environments where noise mitigation matters or for shooters who already run rimfire suppressors, the adapter saves you from buying extra hardware and fitment work. It’s a forward-thinking inclusion that increases the pistol’s utility.

Ambidextrous controls & interchangeable triggers

Ambidextrous controls improve safety and ergonomics for a wider user base. Interchangeable flat and curved trigger options let you tune finger purchase and perceived pull to personal preference — useful if you split time between precision dry-fire work and fast-paced magazine drills. Small changes in trigger geometry can make a big difference in how the pistol feels through strings of fire.

High capacity for a rimfire platform

The P322 is presented as the highest-capacity pistol in its class. For training sessions where you want fewer reloads, this translates into longer uninterrupted practice, better muscle memory development, and fewer disruptions in defensive drills. Capacity and magazine ergonomics are key selling points when comparing rimfire options for extended range use.

Caliber considerations: Why .22LR still makes tactical sense

.22LR remains a cornerstone caliber for low-cost, low-recoil training. The SIG SAUER P322 leverages the affordability of .22LR for high-volume practice while offering a platform that mimics full-size pistol ergonomics. Benefits include reduced shooter fatigue, the ability to focus on fundamentals like sight alignment and trigger control, and the economics of eye-watering numbers of rounds with modest cost per cartridge.

Applications

Use cases include fundamentals training, scenario drills, backyard plinking for marksmanship development, and quiet range days with a suppressor. While not a primary defensive caliber, a well-placed .22LR from a properly trained shooter can be effective; more importantly, the P322 offers a way to practice handgun fundamentals that directly translate to larger centerfire platforms.

Accessories, optics, and setup tips

Because the ROMEOZero Elite comes pre-installed, the P322 is ready for immediate range time. If you plan to add a suppressor, take advantage of the threaded barrel adapter and ensure proper alignment and timing with a competent armorer or gunsmith. Consider keeping both trigger profiles on hand — you may find one setup favors precision dry-fire while the other shines in dynamic drills.
