A quick howto video from Brian at Echo1 which is the tech support video channel of Echo1 USA Airsoft. In this video he shows you how to fix a stuck hammer in an Echo1 Timberwolf Gas Blowback Pistol, you just need to something small that can help you push back the hammer into its place. This also goes for the Tokyo Marui Glock if the same situation happens according to him.

You can find the Echo1 Timberwolf GBB Pistol here.
