The SLR Rifleworks Glock 17 Magazine Extension, GL17-MAG-EXT-17-2, is a precision-machined upgrade for Glock 17 Gen 3–6 and Glock 19X magazines. Crafted from durable 6061 T6 aluminum with a black anodized finish, it adds two additional rounds while maintaining the USPSA 141.25mm legal magazine length. The extension features a contoured profile and subtle texturing to enhance grip and control during reloads.
This magazine extension is ideal for shooters looking to increase capacity for range use, competition, or focused training without compromising reliability. Designed to work with Glock OEM and ETS magazine bodies, it requires a longer-than-stock magazine spring for proper function. The combination of added capacity, secure fit, and refined machining reflects SLR Rifleworks’ reputation for thoughtful design and consistent quality.
