The Umarex Browning Hi-Power Mark III 4.5mm CO2 BB pistol is pretty much all plastic with a few exception but it is actually a very realistic licensed replica of the real steel firearm, if you can ignore it being rather light weight that is. It does have a full size drop out magazine, magazine release, working single and double action trigger and hammer and ambidextrous safety like the original. I would have liked to see this one in all metal and with a working slide but the price is very affordable which offsets the downsides.
