Frequently Asked Questions
Will this magazine work with my Glock 19 or Glock 26?
Yes. This KCI USA magazine is designed to be compatible with all standard Glock 9mm pistols, including the G17, G19, G26, and G34. The extended 33-round body will protrude below the grip on compact models like the G19 and G26, which is intentional — it provides a full-hand grip surface that many shooters find more comfortable and controllable during range sessions.
Is this magazine permanently blocked to 10 rounds, and can it be converted?
This magazine is sold as a California-compliant 10-round blocked magazine and is intended for use in states with magazine capacity restrictions. It is the buyer's sole responsibility to ensure compliance with all applicable local, state, and federal laws regarding magazine capacity. Goodland Guns sells this product in its compliant configuration only.
How does the KCI USA magazine compare to OEM Glock magazines in terms of reliability?
KCI USA is a well-regarded South Korean manufacturer known for producing aftermarket magazines that meet tight tolerances. This Gen 2 magazine features reinforced steel feed lips and has undergone extensive drop, feed, and function testing to ensure reliable performance. While no aftermarket magazine is guaranteed to perform identically to an OEM Glock mag in every firearm, the vast majority of users report smooth feeding and consistent cycling across a wide range of 9mm ammunition types.
