MAGPUL PISTOL MAGAZINE 9MM 17-ROUND CAPACITY
Glock factory mags, the GL9 features entirely polymer construction. Because of this, Magpul GL9 magazines are some of the lightest magazines on the market. Their 17 round magazines come in at 1.7oz, putting them a solid ounce lighter than OEM mags. The 21 round GL9 weighs only 2 ounces flat; a full ounce lighter than OEM 19 round options, and as much as 2.6oz lighter than some +5 extensions. Despite this difference in weight, the form factor is familiar. If you’ve handled a Glock magazine, you have a solid idea of what a GL9 mag is like.
