Rebuild Kit for Mainspring Housing – Officer – Blued

Rebuild Kit for 1911 Mainspring Housing – Officer – Blued

Factory-Correct Performance with Tunable Reliability

First and foremost, the Rebuild Kit for 1911 Mainspring Housing – Officer – Blued provides every internal component required to rebuild or install a mainspring housing in an Officer-size 1911. Specifically, this kit restores factory-new performance while also adding the advantage of a selectable hammer spring weight, a feature exclusive to TMC kits. As a result, you gain both reliability and precise control in a single, well-balanced solution.

Moreover, whether you are restoring a worn carry pistol or completing a fresh custom build, this kit delivers consistent performance from the inside out. Over time, mainspring components inevitably weaken and lose consistency. Consequently, ignition reliability, trigger feel, and overall function suffer. Therefore, this complete rebuild kit corrects those issues by restoring proper spring tension, smooth operation, and dependable ignition.

Complete Factory-Correct Rebuild Solution

Replace Every Wear Component at Once

Unlike partial kits, this Officer 1911 mainspring housing rebuild kit includes all critical internal components needed for a full refresh. Because every wear item is replaced simultaneously, you restore proper function in one straightforward installation. As a result, performance returns quickly and predictably.

Kit Includes

• Precision hammer spring with selectable weight

• Mainspring cap

• MSH  cap pin

• Mainspring housing retaining pin

Taken together, these components restore consistent hammer energy and correct spring tension. As a result, trigger performance improves while ignition reliability stabilizes immediately.

Selectable Hammer Spring Weight

Exclusive Tuning Flexibility

Only TMC kits allow you to choose your hammer spring weight. Because of this, you gain direct control over critical performance characteristics. As a result, tuning becomes both precise and repeatable.

Accordingly, you can fine-tune:

• Trigger feel

• Slide velocity

• Lock time

• Ignition reliability

Therefore, whether you are dialing in a competition pistol or maintaining a duty or carry firearm, this flexibility allows you to balance performance and reliability exactly to your preference.

Precision Manufacturing for Long Service Life

Built for Consistency and Strength

Equally important, each component in this kit is manufactured on high-end Swiss CNC screw machines, ensuring exceptional dimensional accuracy. After machining, every part undergoes a controlled finishing process designed to maximize strength and longevity.

Specifically, each component receives:

• Full heat treatment and hardening

• Centerless grinding for precise fit

• Blued finish for wear resistance and corrosion protection

Because of this process, the components install cleanly, resist deformation, and perform reliably under high round counts.
