Oriskany Arms 1911 Frame – 4.25″ Commander – Classic – Carbon Steel – Standard Ramp

Build a Strong, Reliable 1911 Foundation

Oriskany Arms delivers builders a rugged, American-made 1911 frame that supports premium builds. Furthermore, this 4.25″ Commander frame offers exceptional value, including features usually found on frames that cost two to three times more. Therefore, shooters can confidently use it for defensive pistols, competition-ready builds, or high-end custom projects.

Precision Materials for Long-Term Durability

In addition, Oriskany Arms machines each frame from durable 4140 carbon steel, which provides strength and long service life. First, the company precision-casts the frame, and then CNC-machines it to exact dimensions. Consequently, gunsmiths receive a true-to-spec platform that fits consistently, responds well to tuning, and adapts to custom finishes.

Why Builders Choose the Oriskany Arms 1911 Frame

Precision 4140 Carbon Steel Construction

The frame begins as a 4140 carbon steel casting. Then, Oriskany Arms CNC-machines it with exacting accuracy. As a result, the frame offers a rugged platform that endures heavy use while maintaining clean, consistent dimensions. Furthermore, shooters gain confidence in a frame that performs reliably under demanding conditions.

Oversize Rails for Tight Slide Fit

The oversize frame rails allow gunsmiths to hand-fit the slide for a smooth, precise action. Consequently, the finished 1911 delivers better accuracy and more consistent cycling. Moreover, this tighter fit improves overall performance during rapid-fire sequences and increases reliability.

20 LPI Checkered Front Strap

Oriskany Arms adds 20 lines-per-inch checkering to the front strap. This pattern provides traction without being harsh. Additionally, it improves control during fast strings of fire while remaining comfortable for extended shooting sessions. Therefore, shooters enjoy both functionality and style in every grip.

Heat-Treated for Strength and Machinability

After machining, Oriskany Arms heat-treats the frame to Rc 22–24. Consequently, the frame balances durability with ease of customization. As a result, gunsmiths can modify or tune the frame efficiently, while shooters benefit from long-term performance and reliability.

Trusted American Firearms Manufacturer

Oriskany Arms has produced precision firearm components since 1947. Furthermore, in 2013, the company expanded its lineup to include American-made Series 1911 pistols in .45 ACP and 9mm. Therefore, every frame reflects decades of machining experience and proven firearm engineering, giving shooters a dependable, high-quality platform.
