What gas blowback airsoft pistol should I buy?

I need a gas blowback pistol that is pretty powerful. At least around 330 or 340 FPS with green gas and .2g BB's but any higher FPS would be even better. There is a pistol I found that I want but its 350 FPS with red gas because it's full metal but it's only 300 FPS with green gas, propane and CO2 according to evike.com. Are there any GBB pistols out there that are in the mid to high velocity range or higher with green gas and .2's? Thank you
