OA 1911 Frame – 3.5″ Officer’s Frame – Tactical – W/N Ramp

Oriskany Arms 1911 Frame – 3.5″ Officer’s – Classic
Carbon Steel 1911 Frame with Wilson/Nowlin Ramp

The Oriskany Arms 1911 Frame provides builders with a strong, reliable, and American‑made foundation for a compact Officer‑size 1911. At the same time, this 3.5‑inch Officer’s frame delivers exceptional value by incorporating features typically found on frames costing two to three times more. Consequently, it serves as an ideal starting point for high‑quality defensive pistols, concealed‑carry builds, and refined custom compacts.

Moreover, Oriskany Arms machines each frame from durable 4140 carbon steel to ensure strength and long service life. First, the frame begins as a precision casting. Next, Oriskany Arms CNC‑machines it to exact final dimensions. Because of this tightly controlled process, gunsmiths receive a consistent, true‑to‑spec platform that fits well, tunes easily, and supports detailed customization.

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. As a result, this process creates a rugged platform capable of withstanding heavy use. At the same time, it maintains clean, repeatable dimensions. Therefore, builders can work with confidence throughout every stage of the fitting process.

Oversize Rails for a Tight Slide‑to‑Frame Fit

Additionally, the oversize rails allow gunsmiths to hand‑fit the slide for a smooth and controlled action. Consequently, the finished pistol often delivers improved mechanical accuracy and more consistent cycling. Furthermore, this tighter fit enhances overall reliability, which is especially important in compact Officer‑length 1911s.

20 LPI Checkered Front Strap for Improved Control

The front strap features 20‑line‑per‑inch checkering, which enhances grip without feeling overly aggressive. As a result, shooters gain better control under recoil, particularly with the shorter Officer‑size frame. Meanwhile, the checkering remains comfortable enough for extended training or range sessions.

Heat Treated for Strength and Longevity

Oriskany Arms heat‑treats each frame to Rc 22–24. Because of this carefully chosen hardness, the frame resists long‑term wear while still allowing clean machining and hand fitting. Therefore, builders can modify and tune 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. Consequently, every frame reflects decades of machining experience, engineering expertise, and proven firearm design.
