1911 Jig

1911 Jig

Just as the AR-15’s 80% lower has taken the home gunsmithing world by storm, so too does the new Phantom 80% 1911 jig. This easy-to-use jig kit allows you to cut and drill your own top-tier 1911 frame with little knowledge and simple hand tools. No FFL is required to buy, own, or build your frame using the Phantom jig. 

Building vs. Buying a 1911

Designed and tested by some of America’s best gunsmiths, the Phantom jig is the easiest way to affordably build a 1911 using an 80% frame blank that would otherwise carry a premium price tag at the local gun store. Pair your jig with an 80% 1911 frame and you'll have everything you need to fabricate the foundation for your new .45 ACP or 9mm shooter. All frames listed here are compatible with retail 1911 parts, but we recommend picking up a complete 1911 Build Kit. You’ll have everything you need with one order!

This guide compares 80% 1911 frames and retail frames.

1911 Jig: Tools Required

The Phantom jig and 80% frame require no milling machine or specialty tools to get the job done. All you need to do is make two basic cuts and drill two holes into your frame blank using the Phantom jig. The jig guides your cuts and drilling points for you, so no special measuring or other equipment is required! Each jig includes the necessary drill bits and a handheld cutting car to get the job done. The carbide cutters you need come installed and ready to go right out of the box.

Legal to Build Under Federal Law

Owning and machining a 1911 frame is completely legal in all 50 states with no paperwork required – all you need to do is pick up a frame or build kit and a 1911 jig. It’s time to build America’s most legendary pistol for pennies on the dollar. The ATF classifies the 1911 80% frame as a “receiver blank”, a non-functional piece of metal (not a firearm). Only once you begin machining is the frame blank considered a firearm under federal law. State and local laws may vary. Reference our guide to determine the relevant laws you need to know beforehand. Please note, this guide cannot be construed as legal counsel. If you have additional questions about fabricating a firearm at home, always consult with a licensed attorney in your state.

Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
