The SLR Rifleworks Glock 17 Magazine Extension is a precision-machined upgrade for Glock 17 Gen 3–6 and Glock 19X magazines, adding two extra rounds while maintaining a compact, streamlined profile. Crafted from durable 6061 T6 aluminum with a black anodized finish, this extension features clean lines and subtle SLR branding for a modern, purpose-built look that integrates seamlessly with OEM and ETS magazine bodies.

Designed for shooters who want a bit more capacity without exceeding USPSA’s 141.25mm magazine length limit, this extension is ideal for competition, range use, and focused training sessions. Its textured surfaces and dot matrix pattern promote a secure grip during reloads, while the robust construction stands up to repeated drops and hard use. A longer-than-stock magazine spring is required and sold separately, reflecting SLR Rifleworks’ commitment to reliable performance and thoughtful engineering.
