Full description and what we offer
Stealth Arms manufactures 100% American-made 1911 build kits, frames, parts, and specialized tooling from their facility in St. Marys, Ohio. Founded in 2012, they've grown from a small workshop into a full production operation where every component is machined in-house.
Their flagship product is the 1911 Platypus—a double-stack 1911 frame that accepts either Glock 17 or SIG P320 magazines. This isn't a standard 1911. The Platypus redesign gives you significantly higher capacity while maintaining the 1911 platform shooters know. You can build one from scratch or buy a completed pistol ($1,400).
- •Wide range of Cerakote colors (order free color swatches from Cerakote—just pay shipping)
- •Build your own through their configurator
- •Completed pistols available
- •Additional barrels and parts sold separately
Instead of buying an expensive milling machine to finish an 80% lower, Stealth Arms developed the 1911 Phantom Jig ($199.95). This precision-machined jig eliminates the need for a mill entirely. It's their most talked-about innovation—if you want to build an 80% 1911 without equipment, this is how.
They also offer the Classic Jig for builders who prefer traditional methods, plus replacement cutters for both models.
"Our machinists put their mark on every part they make, and nothing leaves our door without first being inspected."
Every part is CNC machined in-house. This means: - Tight tolerances and perfect fit, right out of the box - Fast turnaround - Ability to catch and fix problems before shipping - Direct quality oversight
Their scrap metal byproduct from machining is collected monthly and 100% of sales proceeds go to charitable organizations aligned with their values.
