Sig Sauer P322 Overview

The P322 is one of the latest pistols from Sig Sauer. The company launched the new .22LR pistol on March 22nd, 2022.

The Sig Sauer P322 is a single-action-only (SAO) firearm built for ease of use. It uses 22 LR rounds, which gives you less recoil compared to a 9mm pistol. The lack of recoil makes the P322 a good choice for beginners, as you can focus on your grip and aim instead of worrying about the kick.

The P322 has a compact frame made with a combination of stainless steel and polymer. It also has a polymer grip and alloy steel slide, which help keep the weight at a reasonable 17.1 ounces. The ambidextrous controls ensure a comfortable grip for left-handed and right-handed shooters.

Sig Sauer P322 Features

Next, we’ll explore a few of the main features of the Sig Sauer P322.

Large Magazine Capacity

The P322 has a 20+1 round capacity, which is the largest capacity available for a compact pistol in the same class. The large capacity is useful at the shooting range. As 22LR rounds are cheaper and you have a large capacity, you can get in more practice.

Removable Rear Sight Plate and Threaded Barrel Adapter

The P322 comes ready for use with a red dot optic and a suppressor without needing separate adapters. The removable rear sight plate allows you to easily add a new sight while the threaded barrel adapter accepts suppressors.

Stainless Steel Frame and Aluminum Slide

Sig Sauer built the P322 from scratch using a new design with a stainless-steel frame and an aluminum slide. The design is rugged and durable. It’s another reliable pistol from Sig Sauer that should hold up to frequent use without the risk of misfiring.


The P365 is a suitable alternative if you’re looking for a 9mm pistol with the same reliability and precision as the P322. The Sig Sauer P365 is more compact but weighs about the same as the P322. You get more power, a smaller magazine, and a crisp trigger.

The Glock 44 is based on the Glock 19 9mm compact pistol but features a hybrid steel and polymer slide. It’s chambered for 22LR rounds and comes with a 10-round magazine. However, it’s significantly lighter compared to the P365. You can also purchase a high-capacity magazine to extend the capacity to 25 rounds.


The Sig Sauer P322 is a recommended pick for those wanting a lightweight pistol for target practice, competition shooting, or their first firearm. It offers minimal recoil and includes a high-capacity magazine, allowing you to concentrate on hitting your target.

The 22LR rounds don’t provide the stopping power that you want for self-defense. However, you may also enjoy using the P322 to hunt small game at short ranges or for plinking.

The P322 is easy to customize to suit your needs. You can add a red dot optic without needing an adapter plate. It also includes a threaded barrel for quickly installing a suppressor.
