1911 Build Kit

1911 Build Kit

Your next 1911 doesn't need to come from those glass counters at the gun store. Thanks to partnerships with industry-leading makers and gunsmiths, we've brought to market some high-end 80% 1911 frames and parts. With all sorts of configurations and parts available, you can now create your own 1911 assembly kit piece by piece.

Build-Your-Own 1911 Kits

To create your 1911 build project, you can pick from our available selection of individual components. Each component is sold separately, allowing you to decide which frame and configuration you want. Choose the parts in each category:

  • 80% frame (Government or Commander)
  • 80% 1911 jig for fabricating frame
  • 1911 parts kit for final assembly
  • Choice of 1911 slide and barrel

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.

State Laws May Vary

Some states have banned 80% lowers and certain firearm parts, or have otherwise restricted the sale and ownership of products we sell. So, be sure to check your local and state laws. We can’t ship our products to certain states. Please check our Shipping & Return Policy before placing an order (see restrictions).

Your build awaits!
