SIG Sauer P322 .22 LR 4″ Optic-Ready Pistol, Black

About this product

The SIG Sauer P322 is a 17.1-ounce, optics-ready .22 LR semiautomatic pistol with a 4-inch barrel, designed from the ground up for training, suppressor use, and introductory shooting. It's a purpose-built system, not a conversion kit, and the modularity—interchangeable trigger shoes, reversible mag catch, Shield RMSc footprint—proves Sig's engineers were thinking about aftermarket support from the start. For the informed shooter, this represents a dedicated rimfire platform that handles like a duty-caliber pistol.

What is the SIG Sauer P322 used for?

The primary use is low-cost, high-round-count training and introducing new shooters to centerfire pistol mechanics. This pistol's 17.1-ounce weight and familiar 1911-style magazine release allow shooters to practice fundamentals without the fatigue or cost of 9mm, while its optic-ready slide caters directly to the modern competitive and defensive training environment. Its threaded barrel (accepts 1/2"x28 muzzle devices) and 22 LR caliber make it one of the quietest hosts available for a suppressor under Title II regulations.

How does the SIG Sauer P322 compare to the Taurus TX22?

The P322 is significantly more modular and suppressor-ready out of the box, but the Taurus TX22 costs about $100 less. Where the Taurus wins is magazine capacity (16-round vs. 10-round standard) and immediate price, but the Sig counters with a factory-threaded barrel, optics-mounting system, and dual-magazine inclusion that the Taurus lacks. For a dedicated trainer where optics mounting or suppression is non-negotiable, the Sig justifies its premium; for pure plinking volume, the Taurus delivers more capacity per dollar spent.

What does it weigh and what are the dimensions?

It weighs 17.1 ounces loaded with a 10-round polymer magazine and measures 7.3 inches in overall length with a 4.1-inch barrel. The slide width is 1.1 inches at its optic-mounting plate, and the grip circumference is 4.8 inches—a configuration deliberately mimicking a compact 9mm like a Sig P365 for muscle-memory transfer. This specific dimensional tuning is why it handles more like a duty gun than a dedicated plinker like a Ruger Mark IV, which has a very different balance profile.

Who is this NOT for?

This pistol is not for shooters seeking maximum magazine capacity in a .22 LR pistol without modification. Its 10-round magazines are a deliberate choice for compliant sale across restrictive states, unlike the Taurus TX22's 16-round standard capacity. It's also a poor choice for anyone not intending to use its modular features—the optic-ready system and threaded barrel add complexity and cost that a basic plinker like a Stevens 334 rifle in .223 would not require for simple range fun.

What's in the box?

You get the pistol, two 10-round polymer magazines, a magazine loader, three interchangeable sight plates (one blank, two with fiber-optic inserts), and both flat and curved trigger shoes. The inclusion of dual trigger shoes and two magazines out of the box is notable—many competitors ship only one magazine—and provides immediate flexibility for shooter preference without additional purchase. Note that the optic-mounting screws and thread protector are also included, stored in the foam cutout alongside the sight plates.

Is the SIG Sauer P322 worth it at $439.99?

Yes, for the shooter who needs the feature set: a suppressor-ready, optics-capable .22 LR that mimics a centerfire pistol's manual of arms. At this price point, you're buying a training tool that allows direct skill transfer to a defensive or competition pistol, not just a recreational plinker. Consider that adding a threaded barrel and optic cut to another rimfire pistol often costs $150-$300 alone, making the P322's factory integration a substantial value if you plan to use those features. If you don't, a simpler option like a basic rimfire revolver or the Stevens 555 Sporting Compact over/under shotgun for clay games may offer more focused utility per dollar.
