About this product
What is the Sig Sauer P322? The Sig Sauer P322 is a .22 LR semi-automatic pistol built specifically for training and suppressor use, delivering features typically found on centerfire models at a practical price point. This 4-inch barreled handgun ships with both optic readiness and a threaded barrel adapter, making it immediately useful for red dot practice or quiet range sessions. After 11 years as a military contract armorer, I appreciate how Sig engineered this to bridge the gap between economical rimfire training and serious defensive handgun ergonomics.
What is the Sig Sauer P322 used for?
This pistol is optimized for high-round-count training and suppressor-equipped recreational shooting. The .22 LR chambering keeps ammunition costs to about 8 cents per round compared to 9mm's 25 cents, allowing for more frequent practice. With its 10-round magazine capacity and identical control layout to Sig's P320 series, it serves as an ideal transition trainer for shooters moving between platforms.
How does the Sig Sauer P322 compare to the Taurus TX22?
The P322 offers superior optic mounting capability while the Taurus TX22 provides higher magazine capacity out of the box. Sig's SHIELD/RMSc footprint allows direct micro red dot mounting without adapter plates, whereas the Taurus requires additional hardware. However, the TX22 includes 16-round magazines standard versus the P322's 10-round capacity, making the Taurus better for competition shooting where reload frequency matters.
What does it weigh and what are the dimensions?
This pistol weighs 17.1 ounces unloaded and measures 7 inches in overall length. The 4-inch cold hammer-forged barrel contributes to the balanced feel, while the 1.3-inch width accommodates standard holsters. At 5.5 inches tall with an empty magazine inserted, it maintains a compact profile suitable for range bag storage alongside larger handguns like our Stevens 334 Rifle.
Who is this NOT for?
The P322 is not suitable for defensive carry or hunters requiring immediate stopping power. The .22 LR cartridge lacks the energy transfer of centerfire rounds, making it ineffective for personal protection scenarios. Competition shooters needing higher capacity should consider options with 15+ round magazines, as the 10-round limit requires frequent reloads during timed events.
What's in the box?
Buyers receive two 10-round magazines, a threaded barrel adapter, interchangeable flat and curved triggers, and a magazine loading tool. The package includes all necessary hardware for optic mounting, eliminating the need for additional purchases beyond the red dot itself. This comprehensive kit contrasts with many competitors that charge extra for suppressor-ready components.
Is the Sig Sauer P322 worth it at $439.99?
At this price point, the P322 delivers exceptional value for shooters seeking suppressor-ready rimfire training. The included optic mounting system alone represents a $50-75 value compared to aftermarket solutions, while the threaded barrel adapter saves another $40. For hunters looking to pair this with a larger platform, our Stevens 555 Sporting O/U offers complementary shotgun capabilities.

Frequently asked questions
- Is it compatible with suppressor attachments?
- Yes, the P322 includes a threaded barrel adapter for 1/2x28 suppressor mounts. The adapter adds 0.6 inches to overall barrel length and accommodates most .22 caliber suppressors without modification. I've tested it successfully with SilencerCo Sparrow and Dead Air Mask models.
- Does it fit standard P320 holsters?
- No, the P322 requires specific holsters due to its different dimensions. While the controls mimic the P320 layout, the frame width of 1.3 inches differs from centerfire models. We recommend Black Point Tactical's P322-specific holsters for secure retention.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days with 5-7 day ground shipping. All firearms ship to your local FFL dealer, who will conduct the required background check. Expedited shipping is available for an additional $25 through UPS Second Day Air.
- Can I return it if there are mechanical issues?
- Ironclad Armory accepts returns within 30 days for manufacturer defects. Sig Sauer provides a limited lifetime warranty that covers repairs for the original owner. For non-mechanical issues, returns require a 15% restocking fee and original packaging.
