Complete Factory‑Correct Mainspring Housing Rebuild Kit

Everything Needed for a Proper Internal Refresh

To begin with, this 1911 mainspring housing rebuild kit includes all critical internal components needed for a full, no‑compromise rebuild. Consequently, you avoid mixing mismatched parts or sourcing components individually.

Kit Includes

• Selectable hammer (mainspring)

• Precision mainspring cap

• Mainspring cap pin

• Mainspring housing retaining pin

Taken together, these components restore correct energy transfer, consistent ignition, and dependable cycling. As a result, the pistol returns to proper function immediately after installation.

Selectable Hammer Spring Weight

Exclusive Tuning Control from TMC

Unlike generic rebuild kits, this blued mainspring housing rebuild kit allows you to select your hammer spring weight. Therefore, you gain precise control over how your pistol feels and functions.

Because hammer spring weight directly affects ignition energy and lock time, this feature allows you to fine‑tune:

• Trigger feel

• Slide velocity

• Lock time

• Primer ignition reliability

As a result, you can set up your pistol for competition speed, duty reliability, or defensive carry confidence. Furthermore, this flexibility ensures the pistol performs exactly the way you intend.

Precision Manufacturing and Heat‑Treated Strength

Built for Consistency and Long Service Life

Equally important, every component in this rebuild kit is produced on high‑end Swiss CNC screw machines for exact dimensional accuracy. After machining, each part undergoes a controlled finishing process to ensure proper fit and durability.

Specifically, each component receives:

• Centerless grinding for precise fit

• Full heat treatment and hardening

• Final surface finishing for smooth operation

Because of this process, the parts install cleanly, resist deformation, and perform reliably under high round counts. Consequently, the kit supports long‑term performance without premature wear.

Durable Blued Steel Construction

Traditional Appearance with Modern Performance

This version features blued carbon steel components, making it an ideal match for traditional blued or parkerized pistols. At the same time, the finish delivers functional benefits beyond appearance alone.

Accordingly, you benefit from:

• Excellent wear resistance

• Reduced glare

• Improved corrosion protection

• Classic factory‑correct appearance

As a result, this rebuild kit blends period‑correct styling with dependable modern performance.
