Ive been checking out the KWC 1911 co2 and it looks awesome for an old school 1911. the finish is great, only problem is that the trades are not engraved, and it shoots hot around 380. but u can get it from asia then. not sure how reliable their airsoft guns are but they make extremely reliable blowback 4.5mm bb guns.
