The .45 ACP Government 1911 80% Frame is CNC-Machined using 7075 heat-treated aluminum. Made from lightweight alloy instead of steel, this frame weighs 60% lighter once finished. It's perfect for customizing any 1911 from the ground up, too, since it's compatible with all regular 1911 parts. Fabrication is required, which can be done with the Steal Arms 1911 Jig.
This is a 1911 frame blank. It is only partially fabricated. It cannot be made to operate in its current state, and is not considered a firearm under federal law. State laws vary. This frame blank is restricted in some states. See shipping restrictions.
