KCI manufactured Glock 17 10Round 9mm Magazine. These are made by KCI and a quality replacement magazine for a Glock. . "DROP FREE" magazines have a HARDENED STEEL INSERT which is encased in a high tech polymer (which is fully metal lined). MANY OTHER MODELS FOR SALE DO NOT HAVE THE STEEL INSERT! DO NOT BE FOOLED INTO THINKING THESE ARE THE SAME MAGAZINE AS OTHERS SELL.
The polymer coating protects the gun magazine and prevents deformation, even when dropped from great heights.
Constructed from steel and polymer just like factory Glock mags.
Compatible Glock 9mm pistols: Glock 17
