The only tool you need to fabricate your 1911 frame confidently.

You don't need to be a professional gunsmith nor do you need access to an advanced milling machine to fabricate a quality 1911 frame at home. With the Stealth Arms Phantom 1911 Jig and an 80% aluminum frame, you'll have the components required to cut and drill that 80% frame, turning it into a finished unit that's ready for a 1911 parts kit.

How the 1911 Jig Works

The 1911 jig provides two primary components: Side plates for securing the 80% frame and drilling the pin holes for the parts kit, and a carbide cutting (operated by hand) to cut the slide rails and barrel seat. Both machining steps combined take approximately 30 minutes to 1 hour for a first-time builder, with no need for measuring or specialty tools.

1911 Jig: What's Included

Your 1911 jig will include appropriately sized drill bits for completing the pin holes, as well as cutting fluid for ensuring the cutting car glides freely over the frame while cutting, without binding or skipping. The only additional tools you'll need are a table vise for securing the frame and jig assembly, and a hand drill for the pin holes.

Compatible with Stealth Arms 1911 80% Frames

Various 80% frames are available for the 1911 platform: Government (5") and Commander (4.25") models provide a full-size or compact/carry profile, with parts kits available in .45 ACP or 9mm Parabellum, magazines included. The Stealth Arms Jig works with all 1911 frames, regardless of size or caliber, and the machining steps are also the same. One jig to build them all.
