KCI USA 17 Round Glock 17 9MM Magazine Black KCI MZ007 UPC 851586008184

Product Description

The KCI USA 17-Round Glock 17 9mm Magazine (KCI-MZ007) is an affordable, high-reliability replacement and extra training magazine built for full-size 9mm Glock pistols and compatible PCC carbine platforms. Engineered to match OEM dimensions and feeding geometry, this 17-round magazine provides reliable round cycling for high-volume range sessions, tactical drills, and general shooting practice.

Constructed with a full-length hardened steel liner encased in an impact-resistant black polymer shell, the KCI-MZ007 prevents magazine swell and deformation even when stored fully loaded under extreme temperatures. A high-tensile chrome-silicon internal wire spring and precision-molded anti-tilt polymer follower ensure consistent upward pressure and smooth, binding-free feeding from the first round to the last.

Featuring standard witness holes along the rear spine for instant round count verification, a removable factory-style floor plate for easy maintenance, and ambidextrous mag catch cuts, this magazine is fully compatible with Gen 1 through Gen 5 Glock handguns, Glock 19X, Glock 34, Glock 45, and aftermarket 9mm PCC carbines accepting standard Glock pattern magazines.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Fits Glock 17, 19X, 34, and 45 (Gen 1–Gen 5). Fits shorter double-stack models (Glock 19, 26) with extended body exposure below the grip frame. Also compatible with AR-9 carbines, Ruger PC Carbine, and Kel-Tec SUB-2000 accepting double-stack 9mm Glock pattern magazines.

1. Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
2. Load 9mm Luger cartridges into the magazine by pressing rounds down and back against the steel feed lips, ensuring rim engagement against the rear spine wall.
3. Insert the loaded magazine firmly into the magazine well until the magazine catch engages with a positive, tactile click.
4. To clean internal components after extended range use, depress the floor plate retaining pin using a punch tool, slide the baseplate forward, and carefully remove the spring and follower assembly.
