Spare magazines for GK Series ACE VR handsets, 3D printed and hand finished. Grab an extra to swap between weights, or pick up a hollow one and load your own. Choose the magazine type that matches your handset grip size, and how much heft you want. Magazine types: • Flush: sits flush with the frame, the standard look for practice and carry setups. • TTI Extended: adds length past the frame and a bit more weight. Weight options: • Unweighted: hollow inside, so you can add your own DIY weights and dial in the balance yourself. • Steel Weighted: heavy, adds real heft for balance. • Lead Weighted: heavier still, closest to a loaded magazine. Most shooters keep a couple on hand: one hollow to experiment with, one weighted and ready to run. Fits GK Series grips: Glock 17 Grip (GK 17, GK 34, GK 45, GK 47), Glock 19 Grip, Glock 17 Gen 6 Grip, and Glock 19 Gen 6 Grip. This is a 3D printed VR training accessory. It is not a firearm and holds no ammunition.
