Oriskany Arms 1911 Frame – 3.5 Inch Officers – Tactical Carbon Steel 1911 Frame – Clark/Para Ramp
A Proven Foundation for High-Performance Officer-Size Builds
The Oriskany Arms 3.5″ Officer’s 1911 Frame provides builders with a strong, reliable, and American-made foundation for premium compact 1911 pistols. Moreover, although designed for the Officer’s format, this frame delivers exceptional value because it includes features often found only on frames costing two to three times as much. As a result, it supports custom builds intended for defensive carry, competition use, or refined personal projects.
Additionally, Oriskany Arms manufactures each frame from high-strength 4140 carbon steel. Then, through precision casting followed by CNC machining, the frame reaches exact final dimensions. Consequently, gunsmiths receive a consistent, true-to-spec platform that responds exceptionally well to custom fitting and tuning.
Why the Oriskany Arms Officer’s 1911 Frame Stands Out
Precision 4140 Carbon Steel Construction
The frame begins as a precision-cast 4140 carbon steel blank. Afterward, Oriskany Arms machines it using CNC equipment to ensure dimensional accuracy. Therefore, the finished frame offers excellent durability while maintaining clean, repeatable geometry throughout critical areas.
Oversize Rails for a Tight Slide-to-Frame Fit
Furthermore, the frame features oversize rails that allow gunsmiths to hand-fit the slide precisely. As a result, the completed pistol achieves a smoother action, tighter lockup, and noticeably improved accuracy. At the same time, consistent slide travel enhances overall cycling reliability.
20 LPI Checkered Front Strap for Enhanced Control
In addition, the front strap includes 20 lines-per-inch checkering. This texture improves grip traction without feeling overly aggressive. Consequently, shooters maintain better control during rapid strings of fire while still enjoying comfort during extended shooting sessions.
Heat-Treated for Strength and Long Service Life
To further enhance durability, Oriskany Arms heat-treats each frame to Rc 22–24. Therefore, the frame balances long-term strength with machinability, making it ideal for custom work while still holding up under hard use.
Backed by a Trusted American Manufacturer
Oriskany Arms has produced precision firearm components since 1947. Moreover, in 2013, the company expanded into a full lineup of American-made Series 1911 pistols in .45 ACP and 9mm. Because of this history, every frame reflects decades of machining expertise and proven firearm engineering.
