Airsoft Headquarters got this lengthy overview of the Elite Force Glock 34 Gas Blowback Pistol. Fully licensed, this is CO2 powered but can also be used it a compatible Green gas magazine. it has a functional Glock trigger safety as well as the slide release... "Just an overview video, especially since I have not been able to use it in a game. I have tons of experience using the G19 and G17 and use them as my secondary regularly."
