G&G Armament have shared details of their new GTP 9 lightweight magazine:

GTP 9 Ver.2 Lightweight Magazine
Lighten your load with the new GTP 9 Version 2 Lightweight 50 Round Magazine. We’ve redesigned the GTP 9 / SMC9 magazine to be constructed out of hard anodized aluminum alloy and reduced the weight from the previous version by 46%. Move and engage enemies faster with a lighter combat load. The magazine is compatible with all GTP 9 GBB Series and the SMC-9 GBB Carbine. Coming soon to your local G&G dealer.
