TMC 1911 Mainspring Housing Pin – Stainless Steel

1911 Mainspring Housing Pin – Stainless Steel

Restore Proper Fit, Alignment, and Long‑Term Reliability

The 1911 Mainspring Housing Pin – Stainless Steel delivers a precision‑fit replacement that restores secure retention and consistent performance. Manufactured from hardened stainless steel, this pin improves frame alignment, stabilizes the mainspring housing, and supports long‑term reliability in both duty and competition pistols. As a result, your 1911 maintains proper function under recoil while remaining dependable through extended use.

Over time, factory mainspring housing pins often loosen or wear. Consequently, housing movement increases, alignment suffers, and overall performance becomes inconsistent. However, this stainless steel replacement pin eliminates those issues by providing a tight fit, superior strength, and smooth installation, which in turn restores proper housing stability and predictable operation.

Precision Swiss CNC Manufacturing

Each mainspring housing pin begins as high‑grade stainless steel and is then machined on advanced Swiss CNC screw machines for exact dimensional control. Moreover, after machining, every pin undergoes a controlled finishing process that includes:

• Centerless grinding for precise diameter accuracy

• Full heat treatment and hardening for increased strength

• Final surface finishing to ensure smooth, clean installation

Because of this process, the pin installs easily, seats securely, and resists wear, even under heavy recoil and high round counts. Therefore, fit remains consistent and performance stays reliable over time.

Built for Strength and Long‑Term Reliability

Unlike softer factory pins, this hardened stainless steel mainspring housing pin resists bending, deformation, and pin walk. Consequently, it maintains proper housing alignment and prevents unwanted movement, which directly supports consistent ignition and smooth operation.

Additionally, this pin handles extended shooting sessions and high‑round‑count use without loss of fit or strength. As a result, it not only improves current performance but also helps extend the service life of your frame and internal components.
