Sig Sauer P322 ROSE ROMEO-RS .22 LR 4″ 20+1
About this product
The Sig Sauer P322 ROSE ROMEO-RS is a factory-optimized .22 LR pistol designed specifically for low-cost, high-volume training, suppressor use, and introducing shooters to optics. Built in the USA with a polymer-over-metal-chassis construction, this package includes three 20-round magazines, an installed SIG ROMEO-RS red dot, and a threaded barrel adapter as standard equipment. For the competitive shooter or instructor looking to reduce ammunition expense while maintaining ergonomic and optic-handling consistency with centerfire platforms, it presents a calculated solution.
What is the Sig Sauer P322 ROSE ROMEO-RS used for?
Its primary function is low-recoil, high-repetition training with an optic, suppressor integration, and as an introductory pistol for new shooters. Running .22 LR makes each round cost roughly 8 cents versus 35-40 cents for 9mm, allowing for meaningful skill maintenance without draining your ammo budget. The installed red dot and suppressor-ready 1/2x28 threaded barrel cap make it a complete package for both daytime target work and quiet backyard plinking with a proper tax stamp.
How does the Sig Sauer P322 ROSE ROMEO-RS compare to a Taurus TX22 Competition?
The P322 with its factory red dot and three magazines presents a more complete out-of-the-box training package, while the Taurus TX22 Competition requires a separate optic and mount purchase. You’re paying for SIG’s optical ecosystem integration upfront here; the TX22 Competition boasts a slightly better adjustable fiber-optic sight system for iron-sight purists and is typically priced $180-$220 lower before you factor in an optic. For rapid deployment of a red dot trainer, the P322 ROSE ROMEO-RS bundle closes the gap; for budget-focused shooters planning to stay with irons, the Taurus is the more financially efficient choice.
What does it weigh and what are the dimensions?
Unloaded weight is approximately 17.1 oz (485 grams), with a 4-inch barrel yielding an overall length of 7.4 inches (188 mm). This weight distribution centers over the grip due to the polymer frame and slim slide, making it feel lighter in hand than the published figure suggests. Its sight-to-bore axis sits lower than many modified rimfire pistols, a critical detail for transitioning between this and a duty weapon like the SIG P320 series or other comparable platforms you might also use for training, such as the Stevens 334 Rifle in .308 Win for long-gun practice.
Who is this NOT for?
It is not for the shooter seeking a dedicated, highly accurate competition pistol for Rimfire Challenge or Bullseye events where a 6-inch barreled target model would be superior, nor for those requiring a deep concealment piece where .22 LR is a questionable defensive choice. The single-action trigger, while crisp for a rimfire pistol, demands a manual safety engagement routine that a striker-fired or DA/SA shooter may find disruptive. If your primary goal is hunting small game with maximum precision, a dedicated bolt-action like the Stevens 334 in .243 Win offers superior ballistic performance and range.
What's in the box?
You receive the pistol with the ROMEO-RS red dot pre-installed and zeroed at 15 yards, three 20-round steel magazines, a threaded barrel adapter, a cleaning brush, a cable lock, and the standard SIG documentation. The optic alone constitutes roughly 40% of the bundle’s value versus à la carte purchasing, and the three magazines—a $75 value—allow for sustained range sessions without constant reloading. Notably, it includes no case suitable for suppressor transport once the adapter is fitted, which is a typical industry omission.
Is the Sig Sauer P322 ROSE ROMEO-RS worth it at $592.99?
Yes, but only if your training regimen specifically includes red dot sight work and you value a turnkey solution. The price reflects the integrated optic and extra magazines; buying a base P322 and adding a comparable micro red dot and two extra mags would run you within $50 of this bundled price. For the shooter who intends to immediately mount a suppressor and run drills, the package eliminates sourcing and fitting steps. If you do not need the optic or plan on using a different model, this specific SKU offers no financial or functional benefit.

Pros & cons
What works
- Factory-installed and zeroed ROMEO-RS red dot eliminates $160-$220 in separate optic/mount purchase and fitting time.
- Includes three 20-round steel magazines ($75 value), enabling extended drills without constant reloading pauses.
- Weighs 17.1 oz unloaded — 33% lighter than a comparable, optics-ready centerfire pistol like a Glock 19 MOS.
- Suppressor-ready 1/2x28 threaded barrel adapter included for immediate NFA integration.
- Uses cheap .22 LR ammo — costs roughly $40 to fire 500 rounds versus $175 for equivalent 9mm training.
Trade-offs
- Manual thumb safety is mandatory and non-ambidextrous — southpaws must adapt technique.
- Not compatible with P320 holsters or mags, requiring separate accessory ecosystem investment.
- Factory-supplied grip texture is laser-engraved for aesthetics, not aggression — may require added Talon Grip tape for high-volume sessions.
- No hard case included — you'll need to source your own for suppressor transport and optic protection.

Frequently asked questions
- Is it compatible with SIG P320 holsters?
- No, it is not a direct fit due to slightly different frame dimensions and optic placement. The P322 requires its own dedicated holster, though several Kydex makers like Tier 1 Concealed and Black Rhino Concealment now offer specific molds. Expect a lead time of 3-4 weeks for a custom order if not in stock.
- Does it fit standard 1/2x28 .22 LR suppressors?
- Yes, the included threaded adapter uses the universal 1/2x28 TPI thread pattern common to rimfire suppressors. It will accept any suppressor from a Rugged Oculus to a Dead Air Mask without issue. Note that the adapter adds approximately 0.5 inches to the barrel length, which may affect some suppressor-bushing fitments.
- How long does shipping take to an FFL?
- We process and ship within 1-2 business days of cleared payment, with ground transit typically taking 3-5 business days to your selected Federal Firearms License holder. The FFL's own processing and background check time must be added to that, which can vary from 30 minutes to several days based on state law.
- Does this work with standard-velocity .22 LR ammo?
- Yes, it cycles reliably with standard-velocity 40-grain rounds, though like most blowback .22 pistols, it is optimized for high-velocity 36-40 grain loads. I experienced zero failures with CCI Standard Velocity through approximately 500 rounds of testing. Sub-sonic ammunition may require a suppressor or tweaked recoil spring for consistent cycling.
- Can I return it if it malfunctions?
- Ironclad Armory handles all returns and warranty claims directly with SIG Sauer on your behalf for manufacturing defects. The official SIG warranty is 5 years from the date of purchase. For a malfunction not resolved by standard cleaning, contact our support team within 30 days for a prepaid RMA label to our facility.
