OA 1911 Frame Officer Classic Stainless Steel Standard Ramp

Oriskany Arms 1911 Frame – 3.5 Inch Officer’s – Classic Stainless Steel 1911 Frame – Standard Ramp

The Oriskany Arms 1911 Frame gives builders a strong, reliable, and American-made foundation for a premium 1911 pistol. This 3.5-inch Government 1911 frame provides exceptional value, especially since it delivers features often found on frames costing two to three times as much. Furthermore, the frame design supports custom builds for both defensive and competition use.

Additionally, Oriskany Arms uses 416R Stainless steel for impressive strength and long service life. Each 1911 frame is precision cast, then CNC machined to exact final dimensions. Because of this, gunsmiths get a consistent, true-to-spec platform that responds well to custom fitting and tuning.

The Oriskany Arms Officers frames feature a full length grip.  Not the normal shorter Officer grip.

Why the Oriskany Arms 1911 Frame Stands Out

Precision 416R Stainless  Steel 1911 Frame

The frame starts as a 416R Stainless steel casting, and Oriskany Arms machines it with CNC accuracy. This combination creates a rugged platform that handles heavy use while offering clean, consistent dimensions.

Oversize Rails for a Tight 1911 Slide-to-Frame Fit

The oversize frame rails allow a gunsmith to hand-fit the slide for a tight, smooth action. As a result, the finished 1911 often produces noticeably better accuracy and more consistent cycling.

20 LPI Checkered Front Strap for Better Grip

The front strap includes 20 Line Per Inch checkering. This machining adds traction without being overly aggressive. Moreover, builders appreciate the improved control it offers during fast strings of fire.

Heat-Treated for Strength and Longevity

Oriskany Arms heat-treats each 1911 frame to Rc 22–24, which helps balance durability and machinability. Consequently, the frame withstands long-term use while still being easy to work on.

A Trusted American Firearms Manufacturer

Oriskany Arms has produced precision firearm components since 1947. In 2013, the company expanded its lineup and introduced a full line of American-made Series 1911 pistols in .45 ACP and 9mm. Therefore, every frame reflects decades of machining experience and firearm engineering.
