Expert review
About this product
The Sig Sauer P322 is a compact .22 LR pistol with a 4-inch threaded barrel, optic-ready slide, and interchangeable trigger shoes, designed for precision training and suppressor use. Built by SIG Sauer in New Hampshire, it features a polymer frame and ships with two 10-round magazines. This configuration balances affordability with aftermarket readiness for shooters seeking a low-recoil platform.
What is the Sig Sauer P322 used for?
The P322 is primarily used for precision training, suppressor-ready plinking, and introducing new shooters to handguns due to its minimal recoil. Its 4-inch threaded barrel accepts standard .22 LR suppressors without an adapter, and the optic-ready slide accommodates SHIELD/RMSc footprints for red dot mounting. At 17.1 ounces unloaded, it's lightweight enough for extended range sessions but stable enough for drills.
How does the Sig Sauer P322 compare to the Taurus TX22?
The P322 outperforms the Taurus TX22 in trigger customization and optic readiness, but the TX22 offers higher magazine capacity at 16 rounds versus 10. SIG's interchangeable flat and curved trigger shoes allow precise fit, while Taurus uses a fixed design; however, the TX22 costs $100 less, making it better for budget-focused buyers. Both share polymer frames and threaded barrels, but the P322's anodized slide finish provides superior corrosion resistance.
What does it weigh and what are the dimensions?
The P322 weighs 17.1 ounces unloaded and measures 7 inches in overall length with a 4-inch barrel. Height is 5.5 inches including sights, and width is 1.3 inches at the slide—compact enough for holster carry but bulkier than subcompacts like the Ruger LCP II. The Picatinny rail adds 0.8 inches of accessory mounting space, suitable for lights or lasers under 4 ounces.
Who is this NOT for?
This pistol is not for hunters needing high-velocity .22 LR performance or competitors requiring extended magazines. The 10-round capacity limits practical use in events like Steel Challenge, where bolt-action rifles dominate precision categories. Additionally, the polymer frame lacks the heft preferred by bullseye shooters, who often opt for all-steel alternatives.
What's in the box?
Included are two 10-round polymer magazines, interchangeable flat and curved trigger shoes, a threaded barrel adapter, and a rear sight plate for optic mounting. SIG ships it with a cable lock and manual, but unlike some competitors, no hard case—expect cardboard packaging. Total contents weigh 2.1 pounds shipped, with magazines accounting for 3.2 ounces each.
Is the Sig Sauer P322 worth it at $439.99?
At $439.99, it's justified for shooters valuing optic readiness and suppressor compatibility, but overpriced for casual plinking. The included threaded adapter and sight plate save $50-$80 versus aftermarket parts, though budget options like the Stevens 555 shotgun offer more versatility for similar cost. If you plan to add a red dot and suppressor, the investment pays off; if not, consider cheaper .22 LR pistols.

Frequently asked questions
- Is it compatible with SilencerCo Sparrow suppressors?
- Yes, the 1/2x28 threaded barrel accepts SilencerCo Sparrow and other standard .22 LR suppressors without adapters. Threads are cut to SAE specifications, requiring 12 lb-in of torque for secure mounting. Avoid dry-fire without a suppressor, as carbon locking can occur after 500 rounds.
- Does it fit Glock 19 holsters?
- No, the P322's 1.3-inch width and 7-inch length exceed Glock 19 dimensions by 0.2 inches laterally. Use SIG-specific Kydex holsters from brands like Black Rhino Concealment; expect 3-5 business days for custom orders. Universal nylon holsters may work but lack retention.
- How long does shipping take?
- Ironclad Armory processes orders in 1-2 business days with UPS Ground, delivering in 3-5 days continental US. Firearms require FFL paperwork adding 24-48 hours for background checks. Alaska and Hawaii shipments take 7-10 days via USPS Priority.
- Can I return it if it doesn't fit?
- No, Ironclad Armory's policy prohibits returns on firearms due to federal regulations. Exchange for store credit is allowed within 30 days if unfired and original packaging is intact. FFL transfer fees are non-refundable, typically costing $25-$50.
- Does this work with Holosun 507K red dots?
- Yes, the SHIELD/RMSc footprint accepts Holosun 507K models with included mounting screws. Zeroing requires 100 rounds for stability, and battery life averages 20,000 hours at medium brightness. Shims are not included—purchase separately if needed.
