You've heard the news: Yes, you can build a 1911 from scratch. To do that, you need an 80% 1911 frame. You, the proud future owner of your custom handgun, will need to perform some basic machining to make the lightweight aluminum frame functional: Cut the slide rails and barrel seat, and drill parts kit pin holes (here's a guide on how to do it)

State Laws May Vary

Some states have banned 80% frames 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).

The Stealth Arms 80% 1911 Jig

To complete those steps, you need an 80% 1911 jig. The Phantom 1911 Jig by Stealth Arms is designed to work all the 1911 frame blanks we sell, coated or uncoated. The jig is a hand tool, providing a special bladed "cutting car" that you'll operate to cut the frame by hand. It also comes with pre-drilled pin hole guides, so there's no measuring or complex calculations required.

Finishing Your Frame

Completing the frame, including cutting the slide rails and barrel seat by hand, is simple: Each frame is constructed from lightweight yet rugged 7075-T6 forged aluminum. Unlike the 1911's original bulky steel frame (which would be almost impossible to machine by hand) the aluminum 80% frame can be completed in 30 minutes to 1 hour. It provides a lighter pistol that feels better, yet it's just as rugged and capable. Grab an 80% 1911 frame and one of our 1911 build kits, each sold separately.
