TMC Sear Pin – Ambi Safety – Stainless Steel

Sear Pin – Ambidextrous Safety – Stainless Steel

Ensure Proper Ambi Safety Clearance and Consistent Trigger Performance

The Ambidextrous Safety Sear Pin – Stainless Steel provides a precision-engineered replacement specifically designed for 1911 pistols equipped with ambidextrous thumb safeties. First and foremost, this sear pin features a flat-cut right side, which allows proper clearance for ambi safety levers. As a result, the safety engages and disengages smoothly without interference, binding, or drag.

Moreover, this pin is manufactured from high-grade stainless steel and fully hardened to restore tight tolerances, smooth trigger movement, and long-term durability. Consequently, both duty and competition pistols benefit from consistent performance and reliable operation.

Precision Swiss CNC Manufacturing

Exact Tolerances for Reliable Fit and Function

Each ambidextrous safety sear pin begins as premium stainless steel stock and is machined on advanced Swiss CNC screw machines for precise dimensional control. Furthermore, after machining, every pin completes a carefully controlled finishing process that includes:

• Centerless grinding to achieve exact diameter consistency

• Full heat treatment and hardening for increased strength

• Final surface finishing to promote smooth operation and wear resistance

Because of this meticulous process, the pin installs cleanly, seats securely, and maintains its shape through extended firing cycles. Therefore, long-term reliability remains consistent even under heavy use.

Designed Specifically for Ambidextrous Safeties

Flat-Cut Profile for Proper Clearance

Unlike standard sear pins, this ambidextrous model incorporates a flat-cut on the right side. Consequently, it provides the necessary clearance for ambi safety levers while eliminating interference. At the same time, this design:

• Prevents binding and unwanted drag

• Maintains smooth, positive safety engagement

• Preserves clean and consistent trigger movement

As a result, pistols equipped with ambidextrous controls retain proper function without compromising trigger feel or safety operation.

Built for Strength and Trigger Consistency

Hardened Stainless Steel for Long-Term Use

Soft factory sear pins can bend, walk, or wear prematurely. In contrast, this hardened stainless steel sear pin maintains precise sear alignment and resists deformation under recoil. Consequently, it preserves proper trigger geometry and protects high-quality trigger work.

Additionally, the hardened construction ensures consistent performance over high round counts. As a result, the pin delivers long-term reliability while supporting crisp, predictable trigger operation.

All pins meet or exceed OEM specifications. Therefore, they perform reliably in both factory and custom-built pistols.
