Product Details

Magpul's Glock magazines rival the reliability and durability of original Glock OEM magazines, with the added benefit of additional capacity and other PMAG platform features. With a 21 round capacity, this double-stack 9mm Glock magazine is perfect for any double-stack Glock pistol or pistol caliber carbine that accepts a double-stack Glock magazine. These Magpul Glock mags are fully loaded with great features: lightweight, fully-polymer with a stainless steel spring, highly visible "controlled-tilt" follower, removable floorplate, paint matrix for marking, and more. For serious competitors, these magazines meet the 140mm requirements for competition magazines. All shooters can appreciate getting a good grip on the magazine for quick changes using the ridged floorplate, as well as using the capacity indicator windows at the 21, 15, and 10 round points to quickly determine how many rounds are left. 

  • Compatible with all full-size, compact, and sub-compact double-stack Glock 9mm variants
  • Drops free when ejected, loaded or unloaded
  • Rugged Magpul polymer, lightweight, and reliable
  • Made in the USA

Get yourself several of these and use the paint matrix to mark some for FMJ or ball, and some for HP defensive loads. These magazines can serve you well in the competition, recreational shooting, or even for law enforcement roles.
