Mine works well on Coleman (US) propane. However, due to my leaving the mag charged for over a week, the seal dried and needed to be lubed.
Stopped in Jungletoy today. They have Co2 replacement mags in, but no idea when the regular extra magazines will be there. :?
The thing shoots very well, and feels almost real with the heavy slide and gas blowback. Green gas won't provide enough oomph to get a whole magazine through.
For 100.00 it's a great pistol.
