Airsoft Panda now has in stock the KJ Works Full Metal CO2 M1911A1 Gas Blowback Pistol. Priced at US$93.00 this has a full metal slide. It is said to have realistic markets, but not the official trades, as it just has the KJ Works and Taiwan engraved on the handgun. This has full metal outer barrel and lower frame, compatible with Tokyo Marui Parts, and produces a strong recoil. Better check with them what the average FPs of this handgun is, especially if you're planning to use this for skirmishes.

The CO2 magazine has to be bought separately, fyi.
