Our Take: This is a factory original single stack, 15 round capacity magazine for 1911, M1911, and MEU WE gas blowback pistols. This magazine is constructed entirely out of metal, and has a flat black finish. This single stack gas magazine is easy to load, with an opening on the front of the magazine for loading BB"s. This magazine is light weight and durable, and is compatible with all WE 1911"s that use a single stack (slim) magazine. Specifications: Material - Full metal Weight - 4.5 oz.
