Keeping Traditions Alive Since 1953

KCI has been making Glock-pattern magazines since the 1980s out of South Korea, and the Gen 2 version is where they really started earning respect in the shooting community. This 10-round 9mm magazine is built around a steel-lined polymer body, which is something that sets KCI apart from most other aftermarket options. That internal hardened steel insert reinforces the magazine against crush and deformation, while the polymer shell keeps weight down and resists corrosion. The result is a mag that feels solid in the hand and holds up under regular range use.
Inside, you get a stainless steel spring paired with an injection-molded anti-tilt polymer follower. That combination does real work in keeping rounds lined up correctly and feeding smoothly. The numbered witness holes run along the rear of the body so you can get a quick round count at a glance without fumbling around, and the flush-fit design means no extra bulk hanging below the grip.
Compatibility is broad. This magazine fits the Glock 17, 17X, 18, 19, 19X, 26, 34, 45, and 47, along with Glock-pattern AR-9 builds, the Kel-Tec Sub-2000 (G17 configuration), the Kriss Vector, and other firearms that accept standard Glock 9mm double-stack magazines. That kind of cross-platform versatility makes it a useful spare to have on hand whether you are running a pistol, a PCC, or both.
KCI backs their entire magazine lineup with a limited lifetime warranty, which adds some peace of mind at this price. These are a smart buy for training, competition, and building out your mag supply without putting a dent in your budget.
This magazine is compatible with a wide range of Glock 9mm pistols, including the Glock 17, 18, 19, 19X, 26, 34, 45, and 47. It also works in Glock-pattern AR-9 builds, the Kel-Tec Sub-2000 in G17 configuration, and the Kriss Vector. Always verify compatibility with your specific firearm before use.
The Gen 2 design was a significant step up from earlier KCI offerings. KCI added a hardened steel liner inside the polymer body, improved the anti-tilt follower geometry, and refined the overall tolerances. The Gen 2 versions have earned considerably better reviews from the shooting community compared to the first-generation mags.
Yes, the KCI-MZ047 is designed to drop free when released. The flush-fit baseplate and overall dimensions closely mirror the OEM Glock magazine profile, so mag changes should feel natural and consistent in any compatible firearm.
The KCI Gen 2 Glock-pattern magazines have developed a solid reputation as range and training magazines. Multiple real-world testers have run hundreds of rounds through them across different Glock-pattern platforms without feeding issues. The steel-lined body, stainless spring, and anti-tilt follower all contribute to consistent feeding performance across various 9mm loads.
Yes, the KCI-MZ047 features a removable baseplate, making it straightforward to disassemble the magazine for cleaning, inspection, or spring replacement. This is the same general configuration used in OEM Glock magazines.
KCI backs their magazine lineup with a limited lifetime warranty. If the magazine has a defect or fails under normal use conditions, KCI will address it. This warranty support adds meaningful value for a budget-priced aftermarket magazine.
