Glock 17/22 – Magazine Extension – +5/+4 Capacity
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Warne built these Glock 17 and Glock 22 magazine extensions for shooters who want more capacity, better handling, and a cleaner setup than the usual bargain-bin junk. These extensions fit factory Glock 17 and Glock 22 magazines and add +5 rounds in 9mm or +4 rounds in .40 S&W, while also giving you a more substantial base for reloads and magazine control.
Available options are organized below under Variants.
Fitment
Fits factory Glock 17 and Glock 22 magazines. Adds +5 rounds to 9mm Glock 17 magazines and +4 rounds to .40 S&W Glock 22 magazines.
Does NOT fit
Does not fit Glock 19/23, Glock 26/27, Glock 43X/48, or non-matching magazine bodies. These are built around factory Glock 17 and Glock 22 magazines, so verify your exact setup before you buy.
What it does
This extension increases magazine capacity while improving magazine manipulation. Warne’s ergonomic shape helps with insertion, and the finger-groove profile gives you a better surface for stripping the magazine if needed.
Why it’s worth it
If you run a Glock 17 or 22 for training, range work, or competition-style use, this is a practical upgrade that actually earns its keep. You get more rounds on tap, a tougher aluminum base than cheap plastic alternatives, and better handling during reloads. The black version is the cleaner mainstream seller. The dark earth version is the better play if you want a finish variant without muddying the product family.
