OA 1911 Frame – 4.25 Inch Commander – Classic – W/N Ramp

Oriskany Arms 1911 Frame – 4.25 Inch Commander – Classic

Carbon Steel 1911 Frame with Wilson/Nowlin Ramp

The Oriskany Arms 1911 Frame gives builders a strong, reliable, and American‑made foundation for a premium Commander‑length 1911 pistol. At the same time, this 4.25‑inch Commander frame delivers exceptional value, offering features often found on frames costing two to three times as much. As a result, it supports high‑end custom builds for defensive, competition, and range use alike.

Moreover, Oriskany Arms machines each frame from durable 4140 carbon steel to ensure long service life and structural integrity. First, the frame begins as a precision casting. Then, Oriskany Arms finishes it on CNC equipment to exact dimensions. Because of this process, gunsmiths receive a consistent, true‑to‑spec platform that responds well to hand fitting and fine tuning.

Why the Oriskany Arms 1911 Frame Stands Out

Precision 4140 Carbon Steel Construction

The frame starts as a 4140 carbon steel casting and then undergoes precise CNC machining. Consequently, this combination produces a rugged platform that handles heavy use while maintaining clean, repeatable dimensions. In turn, builders gain confidence during assembly and fitting.

Oversize Rails for a Tight Slide‑to‑Frame Fit

Additionally, the oversize frame rails allow gunsmiths to hand‑fit the slide for a smooth, precise action. As a result, the finished pistol often delivers improved accuracy and more consistent cycling. Furthermore, this tight fit enhances overall shootability.

20 LPI Checkered Front Strap for Improved Control

The front strap features 20‑line‑per‑inch checkering to enhance grip without feeling overly aggressive. Consequently, shooters gain better control during rapid fire. At the same time, the checkering remains comfortable for extended shooting sessions.

Heat Treated for Strength and Longevity

Oriskany Arms heat treats each frame to Rc 22–24. Because of this balanced hardness, the frame resists long‑term wear while still allowing clean machining and fitting. Therefore, builders can work the frame without sacrificing durability.

A Trusted American Firearms Manufacturer

Oriskany Arms has produced precision firearm components since 1947. Later, in 2013, the company expanded its offerings to include a full line of American‑made Series 1911 pistols in .45 ACP and 9mm. As a result, every frame reflects decades of machining expertise and firearm engineering.
