Upgrade your 1911 build with the Oriskany Arms 4.25″ Commander 1911 frame, which provides a strong, reliable, and American-made foundation. Moreover, it combines exceptional value with features often found on higher-priced frames. Therefore, it supports defensive, competition, and custom builds alike, giving gunsmiths and shooters versatility, precision, and confidence.

Precision Materials for Long-Term Performance

Durable 4140 Carbon Steel Construction

Oriskany Arms crafts each frame from 4140 carbon steel, delivering impressive strength and long-lasting performance. Additionally, precision casting followed by CNC machining ensures exact final dimensions. Consequently, gunsmiths receive a true-to-spec platform that adapts easily to fitting, tuning, and custom work. Furthermore, this solid construction withstands heavy use while remaining reliable for years of shooting.

Optimized Design for Accuracy and Control

Oversize Rails for Tight Slide Fit

The frame features oversize rails, allowing gunsmiths to hand-fit the slide for a tight, smooth action. As a result, the completed 1911 produces improved accuracy, more consistent cycling, and enhanced overall performance. In addition, the rails reduce play and contribute to a more solid feel during rapid-fire sequences.

20 LPI Checkered Front Strap

Moreover, the front strap includes 20 Line Per Inch checkering, which provides secure traction without feeling aggressive. Therefore, shooters maintain better control while firing rapidly, and they still enjoy comfort during long shooting sessions.

Heat-Treated for Durability and Machinability

Oriskany Arms heat-treats each frame to Rc 22–24, balancing long-term durability with ease of custom work. Thus, the frame withstands heavy use while remaining easy to modify. Furthermore, this treatment ensures a reliable, precise foundation for high-performance builds.

Trusted American Craftsmanship

Oriskany Arms has produced precision firearm components since 1947. Moreover, in 2013, the company introduced a full line of American-made Series 1911 pistols in .45 ACP and 9mm. Therefore, every frame reflects decades of experience, engineering, and proven reliability. As a result, shooters and gunsmiths can trust the platform for both competitive and defensive applications.
