Expert review
About this product
The Sig Sauer P322 4″ .22 LR Optic Ready Coyote is a semi-automatic rimfire pistol engineered for high-volume training and suppressor-ready small-bore shooting. Built on a coyote tan polymer frame with ambidextrous controls, it accepts micro red dots and ships with two 20-round magazines. I consider it one of the most purpose-driven .22 LR pistols on the market for shooters who prioritize round count and optic readiness over absolute mechanical precision.
What is the Sig Sauer P322 used for?
This pistol is designed for high-round-count training, suppressor testing, and introducing new shooters to handgun fundamentals. The 20-round magazine capacity reduces reload frequency during extended range sessions, while the 4-inch barrel and single-action trigger provide consistent .22 LR ballistics for practical accuracy at 25 yards. I've used it extensively for low-cost drills that would be prohibitively expensive with centerfire ammunition.
How does the Sig Sauer P322 compare to the Taurus TX22?
The P322 outperforms the Taurus TX22 in optic readiness and magazine capacity but trails in aftermarket support and proven reliability. Where the TX22 uses an adapter plate for optics, the P322's direct RMSc cut provides a lower mounting profile, and its 20-round magazines exceed the TX22's 16-round capacity. However, the TX22 has a larger aftermarket for triggers and barrels, making it more customizable for advanced users.
What does it weigh and what are the dimensions?
The pistol weighs 17.1 ounces unloaded and measures 7 inches in overall length with a 4-inch barrel height of 5.3 inches. This makes it slightly heavier than polymer-framed competitors like the Kel-Tec P17 but balances well with a loaded magazine, reducing muzzle flip during rapid strings of fire.
Who is this NOT for?
This pistol isn't for hunters needing sub-MOA accuracy or competitors requiring match-grade triggers. The single-action trigger breaks at approximately 5.5 pounds with noticeable take-up, making it less suitable for precision bullseye shooting than a bolt-action rifle like the Stevens 334. It's a tool for volume, not microscopic groups.
What's in the box?
You get the pistol, two 20-round polymer magazines, a thread protector, optic mounting screws, and a magazine loader. Notably absent is a hard case—it ships in cardboard packaging, which I consider a cost-saving measure that might disappoint buyers accustomed to Pelican-style protection.
Is the Sig Sauer P322 worth it at $439.99?
At $439.99, it's competitively priced against other optic-ready .22 LR pistols but demands you value its specific features. If you plan to mount a red dot and shoot suppressed, the included threading and optic cut justify the premium over base models. For pure plinking without accessories, a shotgun like the Stevens 555 Sporting Compact might offer more versatility for similar investment.

Frequently asked questions
- Is it compatible with SilencerCo suppressors?
- Yes, the threaded barrel accepts 1/2x28 thread patterns common to .22 LR suppressors like the SilencerCo Sparrow. You'll need to remove the included thread protector before mounting. Always verify thread alignment with a gauge before live fire.
- Does it fit RMSc footprint optics?
- Directly—no adapter plate required for Shield RMSc, Sig Sauer Romeo Zero, or Holosun HS407K optics. The cut is milled to spec, though I recommend using Vibra-Tite on the mounting screws to prevent loosening under recoil over 500+ rounds.
- How long does shipping take?
- Ironclad Armory processes orders within 3 business days, with transit times averaging 5-7 days via FedEx Ground. All shipments require adult signature upon delivery per ATF regulations, so plan accordingly.
- Can I return it if it has cycling issues?
- Yes, within 30 days for manufacturer defects, but .22 LR pistols often require a 200-round break-in period. I'd recommend testing with CCI Mini-Mag ammunition first—many cycling issues resolve with hotter ammo and proper lubrication.
