ProMag Ruger SR22 22 LR 15 Round Extended Steel Magazine Black Oxide RUG A54 UPC 708279017728
Product Description
The ProMag® RUG-A54 15-Round Extended .22 LR Magazine for the Ruger® SR22® (SKU: RUG-A54 / UPC: 708279017728) expands the baseline ammunition capacity of your rimfire pistol by 50 percent without compromising reliable lockup. Engineered to eliminate constant reload pauses during training sessions, tactical rimfire drills, and high-volume target plinking, this extended magazine gives shooters maximum trigger time while preserving the natural balance of the SR22 frame.
Constructed from heavy-gauge, heat-treated high-carbon steel, the magazine body is formed to exacting tolerances with smooth, continuous internal geometry. Finished in a protective black oxide / blued coating, the exterior and interior surfaces offer superior resistance to ambient moisture, acidic handling, and rimfire carbon fouling. The hardened steel feed lips maintain rigorous dimensional stability under repeated slide impact, eliminating the feed lip splay and crack risks associated with all-polymer rimfire designs.
Internally, the RUG-A54 utilizes a low-friction injection-molded follower powered by a heavy-duty, heat-treated chrome-silicone wire spring that guarantees balanced upward tension from the first to the fifteenth round. An integrated thumb-assist loading stud track along the side body allows effortless cartridge staging, while the impact-resistant polymer floorplate extension integrates cleanly with the base of the SR22 grip. Proudly manufactured in the United States, this magazine comes backed by ProMag's lifetime warranty.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits Ruger® SR22® pistols chambered in .22 Long Rifle (.22 LR). CRITICAL: Incompatible with Ruger Mark I, II, III, IV, or 22/45 target handguns; incompatible with Ruger LCP II .22 LR or centerfire SR-series pistols. Rimfire ammunition generates heavy lead and wax fouling; clean the internal magazine column regularly with a dry brush. Do NOT apply wet oils, liquid CLP, or aerosol lubricants inside the magazine tube, as liquid lubricants mix with rimfire wax and powder slurry, causing follower drag. Confirm compliance with local capacity restrictions prior to ordering.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Depress the polymer follower or use the side-mounted loading button to verify smooth, unhindered travel throughout the entire steel body length.
- Load .22 LR cartridges individually, ensuring each rim slides into position forward of the preceding rim (rim-lock prevention) and sits flush against the rear spine.
- Assertively seat the magazine into the Ruger SR22 magwell until the factory ambidextrous magazine catch fully and audibly clicks into place.
- Perform an assertive downward tug on the extended floorplate to verify complete mechanical engagement before dropping the slide or initiating live fire.
Key Features
- Heat-Treated High-Carbon Steel Body: Precision-stamped steel shell resists bending, impact deformation, and feed lip splay under heavy drop and cycling conditions.
- Corrosion-Resistant Black Oxide Finish: Chemical blued finish protects against environmental wear, handling rust, and abrasive rimfire fouling while reducing internal feeding drag.
- 15-Round Rimfire Capacity: Increases onboard round count from the standard 10-round factory baseline to 15 rounds for extended range sessions and steel matches.
- Chrome-Silicone Spring: Heat-treated spring wire retains elasticity and continuous upward presentation force through repeated compression and long staging periods.
- Smooth-Operating Injection-Molded Follower: Optimized follower contouring stabilizes rimfire cartridge stacking and ensures positive slide-lock actuation on empty.
- Integrated Side Loading Button: Features an accessible thumb-assist stud along the side slot for fast, effortless rimfire loading without thumb fatigue.
- Ergonomic Grip Extension Floorplate: Impact-resistant polymer baseplate provides extra grip purchase for positive reloads while acting as an over-insertion stop.
- Made in the USA: Built domestically under strict manufacturing tolerances and backed by ProMag's lifetime manufacturer warranty.
