The AMI Difference

In the world of investment-cast firearms and parts, many believe the finish, strength, and fit often fall short. At AMI Defense, we’re changing that view. Our team brings over 60 years of aerospace casting experience to every product we create.

When we developed our 1911 frames and slides, we used a rigorous First Article Inspection (F.A.I.) process. It’s the same level of testing required for critical aircraft parts. This means you can trust your build to perform flawlessly and last a lifetime.

We also boost the strength of our frames with hot isostatic pressing (H.I.P.). This method uses high pressure and heat to eliminate internal voids and create a uniform grain structure. The result is a frame and slide that look great and handle heavy use without failures.

At AMI Defense, our mission is simple: deliver aerospace-quality firearm components you’ll be proud to carry or add to your collection. Our experience, pride, and dedication go into every part we make, helping home builders, gunsmiths, and family shops build their legacy.

AMI Defense is built on aerospace engineering, fueled by a love for shooting sports, and driven by the goal of helping you build your legend.
