This full metal GBB pistol by WE is based on the world famous 1911 ACP. The grip on this pistol has been widened slightly to allow the use of a hi-capa style magazine which can hold more BBs than a standard 1911 mag. The included magazine holds 28 rounds and is also fully made of metal. This pistol is also compatible with extended 50 round magazines made by WE. The blowback on this pistol is crisp and smooth for a realistic experience when firing the gun. It has a functional thumb safety as well as a functional beavertail safety. The slide locks back after the last BB is fired to notify the shooter that a reload is needed and making it easy to get back in the action when a new magazine has been inserted. The gun comes with a 14mm CCW threaded outer barrel making it easy to attach a variety of barrel extensions/mock suppressors. The grips are textured for a secure grip on the gun. Overall this is a great choice for anyone looking for a quality gas blowback pistol that won't break the bank.
