1911 Short Block – Government -10mm – Classic

1911 Short Block – Government – 10mm – Classic

First and foremost, the Government 10mm 1911 Short Block – Classic gives serious builders, competitive shooters, and professional gunsmiths a powerful head start. Rather than beginning with loose components, this 1911 Short Block arrives with the slide, frame, and barrel already precision fit. As a result, you save valuable build time while also reducing overall cost, yet you still retain complete control over the finished pistol.

Moreover, we assemble every 1911 Short Block using the same components, machining standards, and fitting methods applied to our full custom pistols. Because of this approach, the platform delivers strength, accuracy, and reliability from the very first round. Consequently, this Government 10mm 1911 Short Block is ideal for high‑performance range pistols, hunting handguns, and classic 10mm builds.

Features of the Government 10mm Classic 1911 Short Block

Oriskany Arms Government Frame – 1911 Short Block

At the foundation of the 1911 Short Block, the Oriskany Arms Government frame provides the strength required for 10mm performance. First, Oriskany Arms precision casts each frame from 4140 carbon steel. Next, CNC machining brings the frame to final dimensions. Then, controlled heat treatment to Rc 22–24 delivers the optimal balance of durability and machinability.

Because the frame rails are intentionally oversized, the gunsmith can achieve a tight and consistent slide‑to‑frame fit. As a result, mechanical consistency improves and accuracy increases. Additionally, 20‑line‑per‑inch front‑strap checkering enhances grip control under recoil. Ultimately, this frame gives the 1911 Short Block a robust and dependable base.

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 impact toughness, the slide performs reliably under sustained 10mm use.

Furthermore, front and rear cocking serrations provide a positive grip during slide manipulation. As a result, press checks and racking remain secure in all conditions. In addition, standard dovetail sight cuts allow easy installation of a wide range of classic or performance sights.

Sight Cut Specifications – 1911 Short Block

• Rear dovetail: .495 x 65°

• Front dovetail: .330 x 65°

Because these dimensions follow industry standards, sight selection remains 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 10mm 1911 Short Block features a traditional non‑ramped bushing barrel design, preserving classic 1911 geometry while handling the power of the 10mm cartridge.

Barrel dimensions are slightly oversized to allow for a true match‑quality fit. After machining, each barrel undergoes heat treatment and cryogenic stress relief. 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 remains minimal during cycling. As a direct result, consistency improves from shot to shot.

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, enhancing both accuracy and reliability.

Included Components with the 1911 Short Block

To further streamline your build, the Government 10mm Classic 1911 Short Block includes:

• Recoil system

• Slide stop

Because these components are already fit, final assembly proceeds faster and with fewer adjustments.

Parts Required to Complete the 1911 Short Block

To finish your 1911 Short Block, you will need:

• Plunger tube
