The gas blowback version of the HK45 airsoft pistol from Umarex made by the KWA is featured in this video from OddysAirsoft... "The classic Heckler & Koch large calibre airsoft gun with Polymer body and metal slide, and with full HK trademarks this makes for a truly outstanding replica in both weight and feel. With Gas-Blowback-function of the metal slide, incl. second back-handle for replacement."
