Description
The ETS GLK22170 gives you extra rounds downrange without sacrificing reliability. It's a 24-round extended magazine built in advanced polymer, designed to work with Glock 22, 23, 24, 27, and 35 pistols across Gen 1-4. At 170mm, it's competition legal, so whether you're running drills at the range or testing your setup for match conditions, you've got the capacity to keep shooting without constant reloads.
The translucent polymer body is one of the standout features. You get a real-time view of your ammo count and can even see what type of round you've loaded, which beats staring at small witness dots. The polymer is formulated to handle the rigors of heavy use. It won't crack or break when dropped, stays functional through extreme heat and cold, and resists UV damage that can make plastics brittle over time.
Creep resistance is where this design really shows its durability. Load these mags full and store them for months without worry. The feed lips and body won't spread from long-term pressure, which means reliable feeding when you finally take them to the range. The ergonomic floorplate is wide and easy to grab from a pouch during mag changes, and it's compatible with both Glock and aftermarket extensions if you want to customize your setup.
What you get is straightforward: reliable, durable extended capacity at a fair price point. It's not cutting-edge technology, but ETS has the track record to back up the claims. Range use, training, or competition—these run when you need them to.

Frequently Asked Questions
Will the ETS GLK22170 magazine fit my Glock 22?
Yes. This magazine is designed specifically for Glock 22, 23, 24, 27, and 35 pistols from Gen 1 through Gen 4. All these models are cross-compatible with .40 S&W magazines, so it will work reliably in your Glock 22.
Is this magazine competition legal?
Yes. At 170mm in length, the ETS GLK22170 meets the 140mm competition legal requirement for USPSA and similar shooting sports. You can use it in most competitive matches without restrictions.
What happens if I load this magazine and store it fully loaded for a long time?
The feed lips and body won't spread or deform from the pressure. ETS designed this magazine to be creep resistant, meaning you can store it loaded indefinitely without damaging the magazine or affecting its feeding reliability when you take it to the range.
Can I use a Glock factory floorplate or aftermarket extension on this magazine?
Yes. The ETS GLK22170 uses standard Glock floorplate geometry, so it's compatible with both Glock OEM plates and aftermarket extensions from companies like Vickers Tactical and others. You just swap the baseplate to customize your setup.
How durable is the clear polymer?
The advanced polymer construction is formulated to resist impact, heat, cold, and UV exposure without cracking or becoming brittle. Multiple tests show these magazines continue functioning flawlessly after drops from several feet onto concrete, and the material holds up under abusive range use and long-term storage.
Is there an advantage to the translucent body over solid magazines?
The clear body lets you see your exact round count and ammunition type at a glance, which is much faster than checking small witness holes on opaque magazines. This is especially useful for rapid reloads or during training when you need to know your status immediately.
