Your next 1911 doesn't need to come from those glass counters at the gun store. Nor do you need to pay a premium for a certain brand, only to swap out parts that you don't want in the first place. Thanks to partnerships with industry-leading makers, we've brought to market some high-end 1911 frame blanks for custom builds. With all sorts of configurations available, you can now create your own 1911 piece by piece, truly from scratch.

Quality Aluminum 80% 1911 Frames

Each frame CNC-machined from tough, lightweight 7075-T6 forged aluminum. Frames are available with a sleek hardcoat anodized finish, like you'd find on an AR-15 lower, or you can grab a raw (uncoated) frame and apply your own paintjob or custom coating. Because these frames are made from aluminum, they weigh approximately 50% less than those old, bulky steel frames. They're just a tough and they're compatible with retail 1911 parts, ensuring you can build a custom 1911 without any hassle.

Available in .45 ACP and 9mm

Grab a full-size, 5" (Government) frame for a classic build, chambered in classic .45 ACP or 9mm Parabellum. Frames are optioned with or without an under-slide Picatinny rail, allowing you to attach any tac-light, laser, or other accessories as needed.
