1911 Frame

1911 Frame

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 and gunsmiths, we've brought to market some high-end 1911 frame blanks and an easy-to-use 1911 jig. With all sorts of configurations available, you can now create your own 1911 piece by piece, truly from scratch.

Quality Aluminum 80% 1911 Frames

To create your 1911 build, you can pick from our available selection of individual 80% 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 weight 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.

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.

Pair Your Frame With The Phantom Jig

Stealth Arms provides a quality 80% jig that only requires a hand drill, a vise, and about an hour or two of your free time to complete any of the available frames. Cutting the frame is easy thanks to an included cutting tool that comes with the jig. Easy-to-follow instructions make fabrication guesswork-free and easy for new builders.

This in-depth guide includes jig instructions.

Not a Firearm Under Federal Law

Since the 1911's 80% frame is not fabricated and cannot be made functional without further fabrication, it isn't considered a firearm and requires no FFL for sale or shipment. Once you begin cutting and drilling the frame, it is considered a firearm. Aside from being a convenience, an 80% frame just makes sense for a custom 1911 build: It's made from lightweight aluminum, so it's easy to machine with hand tools. The finish frame is lighter and more ergonomic than a factory steel frame, too. If you are willing to put in an afternoon's worth of work, the pistol you build from scratch will perform like a high-tier retail 1911.
