The Strike Industries Aluminum Mag Plate for Glock 19 extends your magazine capacity without sacrificing the reliable feed and smooth handling that keeps you competitive or ready in the field. Machined from 6061-T6 aluminum, this extended magazine plate adds five rounds to standard OEM Glock 19 (9mm) double-stack magazines—a meaningful boost for shooters who want more rounds on tap during practice, competition, or duty. The low-drag, no-snag geometry is engineered for fast reloads, and the included aluminum locking plate provides extra security once installed.
Strike Industries designed this mag plate with both function and aesthetics in mind. The aggressive lines and unified form factor complement your pistol's profile while the anodized finish is available in BLACKLINE, REDLINE, or FDELINE. Whether you're running a race gun in USPSA competition (the plate fits the 140mm division limit), training hard at the range, or building a duty rig, this plate delivers the capacity you're after without reinventing the wheel.
Installation requires care—this is a tight-fit component that works best with professional gunsmith installation to avoid damage to the magazine body. The kit includes everything you need: the aluminum plate, extended-length spring, locking plate, set screw (M3×8mm), and hex tool. Make sure your local and state laws permit higher-capacity magazines before purchase; this item is restricted in certain jurisdictions.
| Material | 6061-T6 Aluminum |
| Capacity Increase | +5 rounds (9mm) |
| Compatibility | Glock 19 (9mm) OEM double-stack magazines |

The Strike Industries Aluminum Mag Plate is designed for Glock factory OEM G19 (9mm) double-stack magazines only. It is not compatible with G23 (.40 Cal) 10-round magazines or ETS Magazines. If you're using a Strike Industries magwell, the plate has been tested to work with SI magwells.
Strike Industries strongly recommends professional gunsmith installation. The plate is an intentionally tight fit and can damage the polymer magazine body if installed incorrectly. A gunsmith will use proper techniques (typically a small c-clamp) to gently install or remove the plate without harming the magazine. Do not overtighten the locking plate set screw, and contact Strike Industries customer support or a certified gunsmith if you're unsure.
Magazine capacity laws vary by state and locality. This product is not available for shipment to California, Hawaii, New York, and New Jersey residents due to state magazine capacity restrictions. It is your responsibility to verify local and state laws before purchase. Check your jurisdiction's regulations to ensure compliance.
The kit includes one aluminum extended magazine plate, one extended-length spring, one aluminum locking plate, one M3×8mm set screw, one hex tool for installation, and a warning card. Everything needed for installation (by a gunsmith) is included.
