1911 Short Block – Government – 9mm – Classic

1911 Short Block – Government – 9mm – Classic

First and foremost, the Government 9mm 1911 Short Block – Classic gives builders, competitors, and professional gunsmiths a proven head start. Rather than assembling a pistol from individual components, this 1911 Short Block arrives with the slide, frame, and barrel already precision fit. As a result, you save significant time while also reducing overall build costs, yet you still maintain full control over the final configuration.

Moreover, we assemble every 1911 Short Block using the same materials, techniques, and tolerances found in our full custom pistols. Because of this approach, the platform delivers dependable function, consistent accuracy, and long‑term durability right from the start. Consequently, this Government 9mm 1911 Short Block works exceptionally well for range pistols, competition builds, and classic 1911 projects.

Features of the Government 9mm Classic 1911 Short Block

Oriskany Arms Government Frame – 1911 Short Block

At the heart of the 1911 Short Block, the Oriskany Arms Government frame provides strength, balance, and classic handling. First, Oriskany Arms precision casts each frame from 4140 carbon steel. Next, CNC machining brings the frame to exact final dimensions. Then, controlled heat treatment to Rc 22–24 ensures the ideal blend of durability and machinability.

Because the frame rails are intentionally oversized, the gunsmith can achieve an exceptionally tight slide‑to‑frame fit. As a result, mechanical consistency improves and accuracy increases. Additionally, 20‑line‑per‑inch front‑strap checkering enhances grip stability during recoil. Ultimately, this frame gives the 1911 Short Block a strong and economical foundation.

Oriskany Arms Elite Government Slide – 1911 Short Block

To complete the upper assembly, the 1911 Short Block pairs the frame with an Oriskany Arms Elite Government slide. Specifically, we CNC machine the slide from 4140 bar‑stock carbon steel and then heat treat it for strength. Because this alloy offers excellent fatigue resistance and toughness, the slide performs reliably under extended use.

Furthermore, front and rear cocking serrations provide a positive grip when manipulating the slide. As a result, racking and press checks remain controlled and consistent. In addition, standard dovetail sight cuts allow easy installation of a wide range of classic or competition sights.

Sight Cut Specifications – 1911 Short Block

• Rear dovetail: .495 x 65°

• Front dovetail: .330 x 65°

Because these cuts follow industry standards, sight upgrades remain simple and flexible.

Match‑Grade Stainless Bushing Barrel – 1911 Short Block

Oriskany Arms match‑grade barrels are CNC machined in the USA from premium stainless steel bar stock. This Government 9mm 1911 Short Block features a traditional non‑ramped bushing barrel design. Consequently, it preserves classic 1911 geometry while delivering modern reliability.

Barrel dimensions are slightly oversized to allow precise fitting. After machining, we heat treat and cryo stress relieve each barrel. Therefore, internal stresses decrease and barrel life increases. Finally, precision broach‑cut rifling delivers excellent accuracy with all bullet types, including lead.

Precision Fitment in the 1911 Short Block

Slide‑to‑Frame Fit – 1911 Short Block

We hold extremely tight tolerances on every 1911 Short Block slide‑to‑frame fit. Consequently, lateral movement stays minimal during cycling. As a direct result, shot‑to‑shot consistency improves.

Barrel Fit and Lockup – 1911 Short Block

Likewise, each 1911 Short Block includes a hand‑fitted barrel bushing and carefully established lockup. As a result, the barrel returns to the same position every cycle, improving both accuracy and reliability.

Included Components with the 1911 Short Block

To further streamline your build, the Government 9mm Classic 1911 Short Block includes:

• Recoil system
