Airsoft Panda now has in stock the CO2 version of the KWC PT99. They did not indicate the power of this airsoft CO2 pistol, but we'd rather err on the side of caution as we expect this to be "hot" for skirmishing and we'd recommend this for target practice. The slide is metal, and comes with minimum markings. Yours for US$100 if you are into CO2 airsoft pistols.
