Affordable 33 Round Magazine for Glock 9mm Pistols and AR-9 Lowers
Everybody loves a 9mm fun stick. 33 rounds of 9mm loaded into your Glock pistol or compatible AR-9 means a ton of fun at the range, since you’ll spend more time shooting, rather than loading. UTG’s new GL399 magazine brings all the fun you want to the range at an affordable price.

These magazines feature an anti-tilt, high-visibility follower, and a stainless steel spring for reliable feed and function. The body of the magazine is made of glass-filled polymer durability, and also has witness holes so you know how many rounds you’ve got left.
This magazine works with a wide variety of guns, including double-stack Glock pistols, 9mm AR-15s with Glock lowers, the Ruger PCC, Century Arms NAK9, and many more.
Features
• Durable and Impact Resistant Glass Fiber Reinforced Matte Black Polymer Construction
• Anti-tilt High Visibility Blue Follower and High Longevity Stainless Steel Spring for Reliable Feeding
• Left and Right Side Capacity Indicator
• Left and Right Side Magazine Catch Cutouts Compatible with Reversible Magazine Release
• Removable Flared Floor Plate for Quick Disassembly and Easy Maintenance
• For Glock 9mm Double Stack Pistols, Glock Compatible Pistol Caliber Carbines and Large Format Pistols
