Description
Fitting a beavertail grip safety to a 1911 has scared off plenty of first-time builders, and for good reason. Cut too much off the frame ears and there's no going back. The Ed Brown 886 Beavertail Jig is the tool that makes that job approachable, guiding your file so you hit the correct .250 radius on both sides of the frame without over-cutting. It's the same jig Ed Brown designed to install their own beavertail grip safeties, and it works just as well for any beavertail built around that same radius.
How the Brown Beavertail Jig Works
The jig slips into the frame through the thumb safety pin hole, and the buttons screw together to hold everything tight and in place on the gun. From there the process is straightforward: scribe around the buttons, grind or mill close to the line, then hand file right down to the hardened edge. The buttons act as both a cutting guide and a stopping point, so you know exactly how much material to take off the tangs.
Built to File Against
This is a heat-treated tool, hard enough that you can file straight up against it without chewing it up. That's the whole point of a good jig. It gives you a solid reference edge and keeps your file honest. Follow up with a smooth file and a little fine sandpaper for polishing, and you end up with a fit that looks like the gun came from the factory that way.
Why Gunsmiths Reach for the 886 Jig
Beyond the initial install, this jig doubles as a gauge for checking fitment and a finishing aid for cleaning things up. It's a reusable tool, so whether you're building one pistol or working through a bench full of them, it earns its keep. Complete installation instructions are included, which takes a lot of the nerves out of that first cut. Plenty of folks tackle a beavertail install with this jig as their first real gunsmithing project and walk away with professional results.

Frequently Asked Questions
What does the Ed Brown 886 beavertail jig actually do?
It guides you in cutting the frame tangs of a 1911 to fit a beavertail grip safety. The jig produces a precise .250 radius on each side of the frame so you don't over-cut. It works as a cutting guide, a fitment gauge, and a finishing reference all in one.
Do I need power tools to use the Brown beavertail jig?
No, that's part of the appeal. You can complete the job with simple hand tools, though many builders rough out the cut with a mill or grinder first to save time. From there you hand file right down to the hardened jig for the final fit.
Will this jig work with beavertail safeties from other brands?
It's designed for Ed Brown beavertail grip safeties, but it works for any beavertail built around a .250 radius. Before you start, confirm that the radius of your grip safety matches the jig so the fit comes out right.
Is the Ed Brown 886 jig hard enough to file against?
Yes, it's heat-treated so you can file directly up against it without damaging the tool. That hardened edge is what gives you a clean, consistent stopping point. It's built to be reused across multiple installs.
