The Airsoft Masterpiece steel magazine release may be a very solid aftermarket upgrade for TM Spec M1911 or Hi Capa platforms. Made out of steel, this magazine release is far more durable than the metal alloy stock magazine releases of most pistols on the market, and can not affect from use nearly as quickly, if at all. This part may be a great choice if you would like to exchange an already-worn mag release, or simply want the upgrade generally.
