TMC Oversized Hammer/Sear Pin Set – Stainless Steel

Our Oversized Hammer/Sear Pin Set provides Precision Fit • Maximum Trigger Performance • Long-Term Durability

The TMC Oversized Hammer/Sear Pin Set gives 1911 builders a precision-fit solution for tightening critical fire-control components. Unlike standard under-spec factory pins, these oversized pins allow you to fit the hammer and sear to the maximum allowable diameter for smoother rotation, reduced wear, and a cleaner trigger pull.

When pins fit loosely, parts shift under recoil. That movement causes friction, wear, and trigger inconsistency. This oversized pin set fixes that problem by creating a tight, stable pivot point that keeps your trigger running smooth and crisp.

✅ Built to Maximum Diameter for Precise Fitting

TMC machines each pin to the largest diameter allowed by the 1911 part print, without exceeding safe specifications:

• Hammer Pin: .157″

• Sear Pin: .110″

• Barrel Link Pin: .154–.156″

As a result, you get the tightest legal fit possible, improving both function and longevity. Some frames may require light reaming for proper installation.

✅ Precision Stainless Steel Construction

TMC manufactures every pin from high-quality stainless steel and then:

• Heat treats each pin for added strength

• Precision grinds the surface for smooth operation

• Finishes each pin for corrosion resistance

This process delivers smooth rotation, consistent engagement, and long service life under hard use.

✅ Why Oversized Pins Improve Trigger Performance

Loose or worn pins cause flex and drag in the trigger system. That leads to:

• Inconsistent trigger break

• Accelerated sear and hammer wear

• Loss of a crisp trigger pull

These oversized hammer and sear pins lock everything into proper alignment. As a result, you get:

• Smoother hammer and sear movement

• Reduced pivot wear

• Longer trigger life

• Stable trigger pull that stays crisp

This set helps protect the trigger job you paid for.
