The Army Armament SD style pistol is a very modern looking addition to the wide range of Glock style airsoft pistols. The metal SD style slide features front and rear serrations with a window, fibre optic sights and the option to add an RMR plate on top. The lower frame is made from polymer and features a very grippy and rough stippling on contact areas. This pistol has an adjustable hop up, runs well on green gas and is compatible with Tokyo Marui magazines.
