TMC Oversized Hammer/Sear Pin Set – Blued

TMC Oversized Hammer/Sear Pin Set – Blued

The TMC Oversized Hammer/Sear Pin Set – Blued provides 1911 builders with precise control over hammer and sear fit. Unlike factory pins, which often run under size, this oversized set allows exact fitting at the maximum safe diameter. Consequently, rotation becomes smoother, wear is reduced, and the trigger break feels cleaner, more consistent, and reliable.

Over time, loose pins cause movement that leads to friction, accelerated wear, and inconsistent trigger feel. However, this oversized 1911 pin set addresses that problem directly by creating a tight, stable pivot point. Therefore, the fire-control system remains properly aligned, and the trigger maintains a smooth, crisp, and predictable pull throughout extended use.

Oversized to Maximum 1911 Specification

Precision Oversize Dimensions

First, TMC machines each pin to the largest legal diameter allowed by the 1911 part print, all while staying within safe tolerances. This ensures the tightest possible fit without compromising reliability.

• Hammer pin: .157″

• Sear pin: .110″

As a result, trigger feel improves, and component wear decreases. Additionally, some frames may require light reaming to achieve proper installation. Nevertheless, the payoff is a secure, precision-fit fire-control system that outperforms standard pins.

Precision Carbon Tool Steel Construction

Strength, Smoothness, and Corrosion Resistance

Next, TMC manufactures every pin from high-strength carbon tool steel to withstand repeated use under recoil. After machining, each pin undergoes a multi-step finishing process to maximize durability and performance.

First, the pins receive full heat treatment to increase strength and resist bending. Then, precision surface grinding ensures smooth, consistent rotation. Finally, a durable blued finish protects against corrosion while delivering a clean, professional appearance.

Because of this process, the pins pivot smoothly, engage reliably, and remain stable under heavy use. Therefore, you gain both long-term reliability and consistent trigger performance.

Why Oversized Hammer and Sear Pins Improve Trigger Performance

Stability Creates Consistency

When pins are loose or worn, the hammer and sear shift under recoil. Over time, this movement causes inconsistent trigger breaks, accelerated wear, and diminished crispness.

In contrast, oversized hammer and sear pins lock all fire-control components into proper alignment. Consequently, hammer and sear movement becomes smoother, pivot and hole wear is reduced, and trigger life is extended. Most importantly, the trigger pull remains stable, crisp, and reliable, ultimately protecting the precision trigger work you invested in.
