OA 1911 Frame – Officer Tactical Carbon Steel Standard Ramp

Oriskany Arms 1911 Frame – 3.5″ Officer’s – Tactical Carbon Steel

Enhance your next 1911 build with the Oriskany Arms 3.5″ Officer’s 1911 Frame, a strong, reliable, and American‑made foundation engineered for serious builders. Moreover, this frame delivers outstanding value while offering features typically reserved for higher‑priced options. As a result, it suits defensive pistols, competition guns, and full custom projects alike, giving you flexibility and confidence from the very start.

Precision Materials for Long‑Term Reliability

Durable 4140 Carbon Steel Construction

Oriskany Arms machines each frame from 4140 carbon steel, which provides excellent strength and long‑term durability. Additionally, the company combines precision casting with CNC‑machined final dimensions. Because of this process, every frame remains consistent, true to spec, and easy to work with. Consequently, gunsmiths gain a reliable platform that fits properly, adapts easily, and responds well to detailed hand‑fitting.

Optimized Design for Accuracy and Control

Oversize Rails for a Tight Slide Fit

To further enhance performance, the frame features oversize rails. This design allows the slide to be hand‑fit precisely. Therefore, the finished pistol often achieves tighter lockup, smoother cycling, and improved mechanical accuracy. In turn, shooters benefit from better consistency and control.

20 LPI Checkered Front Strap

Furthermore, the front strap includes 20‑line‑per‑inch checkering. This pattern strikes a balance between grip and comfort. As a result, shooters maintain secure control during rapid fire, while still enjoying comfort during extended range sessions or long training days.

Heat‑Treated for Strength and Machinability

In addition, Oriskany Arms heat‑treats each frame to Rc 22–24. This hardness level provides the ideal balance between durability and machinability. Consequently, the frame resists long‑term wear while still allowing gunsmiths to perform custom work efficiently and precisely.

Trusted American Craftsmanship

Oriskany Arms has produced precision firearm components since 1947. Moreover, in 2013, the company expanded into American‑made Series 1911 pistols in both .45 ACP and 9mm. Because of this long history, every frame reflects decades of machining expertise, engineering knowledge, and proven reliability.
