Description
Product Overview
Engineered for shooters seeking a high-capacity rimfire handgun with serious performance, the Rock Island Armory XT Magnum Pro .22 WMR is a standout in its class. This is not a typical plinking pistol; it’s a robust, feature-forward handgun chambered in the potent .22 Winchester Magnum Rimfire (WMR) cartridge. Built on a durable polymer frame with ergonomic G10 grips, it features a 5-inch barrel for improved velocity and sight radius, comes optics-ready for modern shooters, and offers a generous 14+1 round capacity. Ideal for rimfire enthusiasts, varmint controllers, and those seeking a high-performance, low-recoil training or recreational firearm, the XT22 Magnum Pro bridges the gap between standard .22 LR handguns and larger centerfire calibers.
Key Features
- Potent .22 WMR Chambering: Fires the .22 Winchester Magnum Rimfire, a cartridge known for significantly higher velocity and energy than standard .22 Long Rifle, resulting in a flatter trajectory and greater terminal effect for small game and pest control.
- Optics-Ready Slide: The slide is machined from the factory with a mounting platform, allowing you to directly install a micro red dot sight without the need for aftermarket milling. This enables faster target acquisition and enhanced accuracy for competitive shooting or hunting.
- High-Capacity 14-Round Magazine: Offers substantial firepower between reloads, an advantage in training scenarios, rimfire competition stages, or extended pest control sessions where multiple targets may be present.
- Premium G10 Grip Panels: Provides a supremely secure and textured hold in all weather conditions. G10 is a high-pressure fiberglass laminate known for its durability, moisture resistance, and aggressive grip texture that aids in control, especially with the snappier .22 WMR round.
- 5-Inch Barrel: The longer barrel length maximizes the velocity potential of the .22 WMR cartridge, contributes to a longer sight radius for iron sight accuracy, and aids in muzzle control and balance.
- Durable & Ergonomic Design: Built with a reliable blowback action and a user-friendly control layout, the handgun is designed for consistent function and comfortable handling, making it suitable for shooters of various experience levels.
Performance & Applications
Small Game Hunting & Varmint Control: The .22 WMR round, when fired from the XT22 Magnum Pro’s 5-inch barrel, delivers ethical takedown power for small game like rabbits and squirrels at extended ranges compared to .22 LR. Its higher capacity is also beneficial for managing pest populations such as ground squirrels or raccoons around a property, where follow-up shots may be necessary.
Low-Cost, High-Volume Training: While .22 WMR is more expensive than .22 LR, it remains far more economical than centerfire ammunition. This pistol allows shooters to practice fundamental skills—sight alignment, trigger control, and rapid follow-up shots—with manageable recoil and operating cost. The optics-ready platform is perfect for practicing with a red dot sight system without the expense of centerfire round counts.
Rimfire Competition & Recreational Shooting: For action shooting sports with a rimfire division, the XT Magnum Pro’s capacity, ergonomics, and optics-ready feature make it a capable contender. It transforms a day at the range into a high-fun, low-fatigue experience, allowing for extended practice sessions focused on skill development and marksmanship.

Product quality is solid but the website could use some work. Hard to find what I was looking for at first. The Rock Island Armory XT Magnum Pro .22 Mag 5″ Barrel 14-Rou… itself? No complaints.

Been in the market for a while and finally decided to buy from Jovinogunshop. I was comparing this against similar products from eBay and decided to take the chance. Glad I did. Arrived in 2 days, well-packaged, and the quality speaks for itself. Installed it on my G19 Gen3 and ran 114 rounds through it without a single hiccup. This is the real deal.

Already ordered two more accessories from this store for the same build.
