1911 Short Block – Government – 10MM – Tactical

1911 Short Block – Government – 10MM – Tactical

First and foremost, the Government 10MM Tactical 1911 Short Block gives serious shooters, competitive builders, and professional gunsmiths a powerful and reliable starting point. 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 valuable time, reduce labor costs, and still retain complete control over the final configuration.

Moreover, we assemble every 1911 Short Block using the same components, machining standards, and fitting techniques applied to our full custom pistols. Because of this approach, the platform delivers strength, accuracy, and durability from the very first round. Consequently, this Government 10MM 1911 Short Block excels in tactical builds, hard‑use pistols, and high‑performance 10MM applications.

Features of the Government 10MM Tactical 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 high‑pressure 10MM loads. 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 ensures an ideal balance of strength and durability.

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, front‑strap checkering enhances grip control under recoil. Ultimately, this frame gives the 1911 Short Block a rugged and dependable foundation.

Oriskany Arms Elite Tactical Slide – 1911 Short Block

To complete the upper assembly, the 1911 Short Block pairs the frame with an Oriskany Arms Elite Tactical slide. Specifically, we CNC machine the slide from 4140 bar‑stock carbon steel and heat treat it for durability. Because this alloy provides excellent fatigue resistance and impact strength, the slide performs reliably under sustained 10MM use.

Furthermore, aggressive front and rear cocking serrations deliver a positive grip during manipulation. As a result, slide operation remains secure even in adverse conditions. In addition, standard dovetail sight cuts allow easy installation of tactical, duty, or competition 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 and installation remain straightforward.

Match‑Grade Stainless Barrel – Tactical 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 fully supported ramped barrel designed to handle high‑pressure cartridges. Consequently, it improves feeding reliability and enhances chamber support.

Barrel dimensions are slightly oversized to allow for a precise, match‑quality fit. After machining, we heat treat and cryo stress relieve each barrel. Therefore, internal stress decreases and barrel life increases. Finally, precision broach‑cut rifling delivers excellent accuracy with all bullet types, including defensive and duty ammunition.

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 carefully fit barrel and established lockup. As a result, the barrel returns to the same position every cycle, improving both accuracy and long‑term reliability.

Included Components with the 1911 Short Block

To further streamline your build, the Government 10MM Tactical 1911 Short Block includes:

• Recoil system
