The ETS GLK-21-18 magazine represents a modern approach to pistol magazine design. Built from advanced polymer rather than traditional steel, this 18-round magazine for the Glock 21, 30, and 41 offers distinct advantages for shooters who demand durability and dependability.
While steel magazines have their place, modern polymer construction offers real-world advantages. The ETS magazine won't rust, requires no lubrication, and resists the chemical exposure that can degrade traditional magazines over time. The translucent design is particularly valuable—you'll always know your round count without removing the magazine from your pouch.
ETS magazines are engineered for shooters who expect their gear to perform in demanding conditions. Whether you're at the range, in competition, or relying on your firearm for personal protection, this magazine delivers the reliability that matters.
