The .45 ACP Government 1911 80% Frame is CNC-Machined using 7075 heat treated aluminum. We construct our 1911 80% frames from aluminum to cut down on the weight which results in a frame 60% lighter than a steel 1911 frame. Using a lightweight frame allows for practical everyday carry situations.
Another benefit to an aluminum 1911 80% frame is the ease of finishing the frame, a steel frame can leave builders frustrated and greatly increases the time of your build. Whether you are finishing your 1911 frame with a handheld jig, drill press, or milling machine an aluminum frame will save you time in the end.
The 1911 frames are only 80% completed which allows us to ship them directly to your door, NO FFL REQUIRED. Once the 80% frame is completed it is now by definition a firearm, at this point it falls into the legal definition of a firearm. If it is legal for you to own a firearm, then it is 100% legal for you to build your own firearm.
