Why the P322-COMP is a Smart Choice for Your Rimfire Rig
In my years of building competition guns and coaching new shooters, I’ve seen a lot of accessories come and go. What makes the P322-COMP stand out isn’t just its name; it’s its specific, effective design. A .22 LR doesn’t have heavy recoil, but managing that quick, sharp muzzle flip is the key to speed. This compensator uses a multi-port design to redirect gases upward, actively countering that rise. The result? Your sights settle back on target quicker. For a family looking to get into Steel Challenge or a seasoned shooter wanting to drill fundamentals, that flat-shooting characteristic translates directly to better scores and more confident shooting. It’s the upgrade that turns your reliable P322 into a dedicated performance tool.

How the P322-COMP Stacks Up Against the Competition
Not all comps are created equal. I’ve fitted everything from bargain-bin parts to full-custom race guns. Here’s a straightforward look at where the P322-COMP lands.
| Feature | P322-COMP | Generic Aluminum Comp (~$65) | High-End Titanium Comp (~$250+) |
|---|---|---|---|
| Material | High-Grade Aluminum | Basic Aluminum | Aerospace-Grade Titanium |
| Quality & Fit | Precision CNC, perfect thread match for P322 | Often loose tolerances, may require shims | Exceptional fit and finish, often custom-timed |
| Compatibility | Designed specifically for the SIG P322 | “One-size-fits-many” 1/2″-28 thread | Usually model-specific or custom |
| Shipping & Availability | In stock, ships same-day from TX | Varies, often ships from overseas | Long lead times, often made-to-order |
| Lifespan & Durability | Hard-anodized for long life with .22 LR | Basic finish, may wear quickly | Extremely durable, nearly indestructible |
| Price Point | $605.15 (on sale) | ~$65 – $80 | $250 – $400+ |
The P322-COMP hits the sweet spot. It’s not the cheapest option, but those generic comps can be a headache with fitment and offer inconsistent performance. The high-end titanium comps are fantastic, but for a .22, they’re often overkill and come with a steep p322-comp price. This SIG-designed unit gives you guaranteed compatibility, proven performance, and quality construction at a reasonable investment.
The Real-World Pros and Cons
Based on handling and installing these, here’s my take:
Pros:
- ✅ Noticeably Reduces Muzzle Rise: The primary job. You’ll feel the difference, especially during rapid strings of fire.
- ✅ Factory Direct Fit: No guesswork, shims, or alignment issues. It threads on cleanly and indexes correctly.
- ✅ Lightweight: Adds almost no perceptible weight to the front end, preserving the pistol’s natural balance.
- ✅ Durable Finish: The hard-anodizing stands up to holster wear and frequent mounting/removal.
- ✅ Enhances Training Value: A flatter-shooting gun helps shooters of all levels focus on technique, not fighting the pistol.
Cons:
- ❌ Adds Length: This will affect holster fit. Most generic p322 comp holster options for the threaded barrel may not accommodate it. You’ll likely need an open-bottom competition-style holster.
- ❌ Specific Use Case: It’s a dedicated competition/training accessory. For a purely plinking or hunting setup, it’s an extra component that might not be necessary.
Who Should (and Shouldn’t) Buy the P322-COMP
Buy it if:
- You use your SIG P322 for rimfire competition leagues like Steel Challenge or NRL22.
- You’re a shooting instructor or coach using the P322 as a training tool and want to minimize student frustration with muzzle control.
- You’re a recreational shooter who wants to experiment with performance upgrades and shoot faster, more accurate groups.
- You appreciate gear that is designed to work seamlessly with your specific firearm.
Skip it if:
- Your P322 is solely for casual plinking and you have no interest in competitive timing or advanced drills.
- You need a completely concealed carry package. The added length makes concealment impractical.
- You’re on an extremely tight budget and the core function of the pistol (reliable shooting) is all you need. In that case, invest in more ammo and practice first.
Common Questions and Concerns
Will this work with my P322’s suppressor? No. You must remove the compensator to attach a suppressor. They are mutually exclusive muzzle devices.
Does it make the gun louder? To the shooter, it can direct some sound and gas sideways/upwards, which may be perceived differently. To bystanders, the report is largely unchanged.
Will it cycle standard velocity ammo? The P322-COMP is very efficient and does not rely on gas operation, so it should not affect the pistol’s reliability with any standard 22 LR ammo.
Frequently Asked Questions
Is the P322-COMP easy to install myself?
Absolutely. If you can safely clear your pistol and field-strip it, you can install this. It simply threads onto the existing 1/2″-28 threads on your P322 barrel. Hand-tighten it until it indexes correctly (lines up). No special tools are required, but a small amount of copper anti-seize on the threads is a good practice to prevent galling.
Does the P322-COMP make a significant difference in performance?
Yes, particularly in timed or rapid-fire scenarios. The reduction in muzzle climb allows for faster sight recovery. For new shooters, this means less time fighting the gun and more time learning proper mechanics. For experienced competitors, it can shave precious tenths of a second. Check out any detailed p322 comp review online, and you’ll see users confirm the tangible benefit.
Will this fit a P322 Compact model?
This is a common point of confusion. The “COMP” in P322-COMP stands for “Compensator,” not “Compact.” This compensator is designed for the standard SIG Sauer P322 with a threaded barrel. There is not currently a p322 compact model from SIG Sauer, so this accessory is for the standard, full-size P322 pistol.
Do I need a special holster for my P322 with the compensator attached?
Most likely, yes. The added length means a standard holster for the P322 (even one for the threaded barrel) will likely not fully cover the muzzle. You will want to look for a competition-style holster with an open bottom or one specifically designed to accommodate a compensated P322.
Is the compensator worth the investment for a .22 pistol?
That depends on your goals. For pure plinking, maybe not. For any form of competitive shooting or serious skill development, I believe it is. The fundamentals you learn shooting a flat .22 translate directly to centerfire pistols. Any tool that helps you learn those fundamentals faster and more effectively is a worthwhile investment in your shooting ability.
Can I use this compensator in sanctioned competitions?
In most practical shooting sports like Steel Challenge or USPSA Rimfire, compensators are allowed and common. Always check the specific rulebook for the league you are entering, but for the vast majority of rimfire p322 competition events, the P322-COMP is a legal and competitive accessory.

Installed it on my G19 Gen3 the same day it arrived. Good lockup. Couldn’t be happier with this purchase.

Bought this as part of a larger build project. Californiagunshop had the best price by a decent margin and shipping was fast. The P322-COMP itself is well-made — Smooth cycling. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
