Cross Armory CRG+5 Glock 17 Magazine Extension +5 Rounds Black

The Cross Armory CRG+5MEG17BK Magazine Extension transforms standard Glock 17 magazines into higher-capacity platforms with an additional 5 rounds. This precision-engineered aluminum extension maintains the magazine's original reliability while providing tactical advantages for competition shooters and law enforcement professionals.

What Makes This Different

Unlike polymer alternatives that can crack under stress, this extension features CNC-machined 6061-T6 aluminum construction with a Type III hard anodized finish. The proprietary spring system maintains consistent feeding pressure across all 22 rounds, eliminating the feeding issues common in other magazine extensions. Internal dimensions match factory Glock specifications to ensure seamless integration with existing magazines.

Range testing demonstrates consistent feeding across various ammunition weights from 115gr to 147gr.

Competition shooters report improved stage times with fewer reloads, while the robust construction withstands repeated dropping on concrete surfaces.
