1911 Short Block – Officer Tactical – 9MM

1911 Short Block – Officer Tactical – 9MM

The 1911 Short Block – Officer Tactical in 9MM gives builders and gunsmiths a faster, smarter way to start a custom pistol. Whether you are a do-it-yourself shooter or a professional gunsmith, this kit saves time, reduces fitting work, and delivers proven quality from the beginning.

Instead of starting with mismatched parts, each Short Block includes a matched slide, frame, and barrel. Moreover, we fit these components using the same methods and tooling found in our full custom builds. As a result, you gain precision, consistency, and reliability—while keeping your project efficient and affordable.

Built for Serious Custom Builds

Our Short Blocks combine premium materials with careful fitting to create a dependable foundation for your next 1911 project. Because the critical components already work together, you can focus on tuning, finishing, and personalization rather than correcting basic fit issues. In turn, this approach saves valuable bench time and reduces frustration.

Precision Frame – Oriskany Arms

The Oriskany Arms 1911 frame offers features typically found on frames costing two to three times more. Additionally, it provides the strength and durability required for long-term performance.

• Precision cast from 4140 carbon steel

• CNC machined to final dimensions

• Heat treated to Rc 22–24 for optimal durability

• Oversize frame rails allow an exceptionally tight slide-to-frame fit

• 20 LPI front strap checkering improves grip and control

Because of this design, the frame delivers a strong, economical foundation for a reliable and accurate all-around shooter.

Elite Slide – Strength and Control

TMC Elite 1911 Slides start from 4140 bar-stock carbon steel and then undergo precision CNC machining and heat treatment. As a result, they offer excellent strength and durability without sacrificing smooth operation.

• High strength and fatigue resistance

• Excellent toughness and impact resistance

• Front and rear serrations for positive grip

• Standard dovetail sight cuts

  • Rear: .495 x 65°

  • Front: .330 x 65°

Therefore, the slide racks smoothly and provides consistent control under all conditions.

Match-Grade Barrel and Bushing

TMC match barrels are CNC machined in the USA from premium stainless steel bar stock. Furthermore, they feature slightly oversized dimensions to promote tighter lockup and improved accuracy.

• Heat treated and cryo stress-relieved

• Precision broach-cut rifling

• Excellent accuracy with all bullet types, including lead

In addition, each Short Block includes a hand-fitted barrel bushing, which ensures strong lockup and repeatable performance.

Precision Fit Where It Matters Most

• Slide-to-Frame Fit: Held to extremely tight tolerances for smooth cycling and improved accuracy

• Barrel Fit: Hand-fitted bushing provides consistent lockup and reliability

Moreover, the kit includes the recoil system and slide stop, further reducing build time and simplifying assembly.

Parts Required to Complete the Build

To finish your Short Block, you will need the following components:

• Plunger tube

• Mainspring housing and magazine release

• Hammer, sear, sear spring, and disconnector

• Trigger

• Thumb safety and grip safety

• Firing pin, firing pin spring, and firing pin stop

• Extractor and ejector

• Complete 1911 pin kit

Why Choose a TMC Short Block?

Because this Short Block uses the same fitting standards as our full custom builds, it delivers accuracy, reliability, and long-term value in one package. In short, it removes the hardest part of a 1911 build while still leaving complete freedom for customization.
