P322 Comp
About this product
The Sig Sauer P322-COMP is a purpose-built .22 LR competition pistol that comes out of the box with the gear most rimfire shooters spend months adding themselves: a factory-milled dual-port compensator, a ROMEOZero Elite red dot already zeroed to the slide, and two magazines — a 20-rounder and a 25-rounder — so you are not stuck hunting for extra mags before your first range trip.
What makes the P322-COMP different from a standard P322?
The COMP variant starts with the same polymer-frame, hammer-fired action as the standard P322 but adds a four-inch barrel wrapped in a two-port compensator machined directly into a two-tone competition slide. The compensator vents gas upward through both ports to counteract muzzle rise, which is the main thing slowing down rapid .22 LR follow-up shots. Sig also fitted an adjustable trigger shoe, an extended magazine catch, and a built-in 1913 accessory rail on the polymer grip module, all details borrowed from Sig's centerfire competition guns rather than a basic rimfire plinker.
What is the P322-COMP good for?
This pistol is built for rimfire steel challenge, USPSA/IPSC rimfire divisions, and high-volume practice where low ammo cost matters more than raw stopping power. The factory ROMEOZero Elite red dot means you are not paying extra or hunting for a compatible mounting plate, and the two included magazines (20-round and 25-round) let you run longer strings of fire before reloading. It is also a genuinely fun range gun for shooters who want to practice trigger control and dot tracking without burning through centerfire ammo prices.
Is the P322-COMP a good choice for a first pistol?
Because it is chambered in .22 LR, recoil and noise are both mild compared to a centerfire handgun, which makes it easier to focus on the fundamentals: grip, trigger press, and sight (or dot) alignment. The single-action, hammer-fired trigger is lighter and more consistent than most striker-fired rimfire guns, which is part of why it is popular with people training specifically for competition trigger control. Keep in mind that .22 LR is not considered a serious defensive round, so this is a range and training gun first.
Every P322-COMP sold here ships to your local FFL for the required transfer and background check — it does not ship directly to a home address. That is standard federal procedure for any firearm purchase, not a delay specific to this listing. California requires new handgun models to be listed on the state's approved roster before they can be sold by a licensed dealer here. Roster status changes over time, so confirm with your FFL that this exact model and configuration is currently approved before you place an order.
What should I check before buying?
Confirm your local range allows compensated pistols (some indoor ranges restrict muzzle devices), and make sure you already own or plan to buy .22 LR ammunition in bulk, since that is most of the cost savings this gun is built around. Beyond that, this is a straightforward, well-specified rimfire competition pistol from a major manufacturer.
Ammunition choice matters more with .22 LR than with centerfire calibers, since rimfire cartridges vary noticeably in reliability from brand to brand. Most owners find a bulk-pack range load that cycles reliably in the P322-COMP and stick with it for practice, saving premium match ammunition for actual competition days. Keep the compensator ports clear of excess lubrication and carbon buildup, since rimfire ammunition tends to leave more fouling behind than centerfire loads and a dirty compensator can affect how consistently gas vents from each port.
Holster and case options built specifically for a compensated slide are less common than for a standard-profile pistol, so if you plan to carry the P322-COMP to the range in a hip or chest holster rather than a range bag, double-check that any holster you buy is cut for the COMP's slide profile rather than the standard P322.
FFL transfer required
This item is a firearm and ships only to a licensed FFL dealer, never to a home address. At checkout, enter your preferred dealer as the shipping address, or leave it blank and we will assign a licensed dealer near you at no extra cost. You complete the background check and paperwork with the dealer when you pick up.
California buyers: handguns must be on the California roster for delivery to a California FFL, a Firearm Safety Certificate (FSC) and DROS are handled at the dealer, and the 10-day waiting period applies. Out-of-state buyers receive the firearm through their own local FFL under their state's rules.

- Is this a good gun for USPSA or steel challenge rimfire divisions?
- Yes, the compensator, adjustable trigger shoe, and factory red dot are aimed squarely at rimfire competition shooters.
