Elite Tactical Systems Glock 17 19 26 34 9mm Magazine - 31 Round (Blue)

Fits Glock 17, 19, 26, 34

This Elite Tactical Systems magazine makes for an excellent companion to your standard Glock factory magazines. ETS uses a durable polymer that is tested to be resistant to warping, cracking, and breaking, in addition to being clearly transparent and excellent for quickly determining how much ammo remains in the mag. The internal springs are excellent for remaining loaded and won't bend or wear down from being under tension. Taking an ETS magazine apart for cleaning and maintenance is simple, as their baseplates are designed to be great for quick reloads, in addition to simple field stripping. 
 

This blue transparent extended mag could be a great choice for containing a special stack of heavier grain-weight rounds, or marking your defensive hollow-points apart from the FMJ mags.
