TMC Sear Pin – Stainless Steel – Hardened

Sear Pin – Stainless Steel

Restore Precise Sear Alignment While Enhancing Trigger Consistency

The 1911 Sear Pin – Stainless Steel delivers a precision-machined replacement that, first and foremost, restores correct sear alignment and smooth, repeatable trigger movement. Moreover, it reinforces long-term reliability by stabilizing critical internal geometry throughout extended use. Additionally, because it is manufactured from high-grade stainless steel and fully heat treated, this sear pin provides the strength, corrosion resistance, and dimensional accuracy demanded by serious shooters and professional gunsmiths alike.

Over time, soft or worn factory sear pins gradually allow movement and misalignment. Consequently, trigger feel becomes inconsistent, pivot surfaces wear prematurely, and overall reliability begins to decline. However, this hardened stainless steel replacement directly corrects those issues. By combining exact tolerances with durable construction, it restores stability, predictability, and long-term confidence in your trigger system.

Precision Swiss CNC Manufacturing

Exact Tolerances for Consistent Fit and Smooth Operation

Each 1911 sear pin begins as premium stainless steel and is then machined on advanced Swiss CNC screw machines for precise dimensional control. Furthermore, once machining is complete, every pin undergoes a tightly controlled finishing process that includes:

• Centerless grinding to ensure precise and repeatable diameter accuracy

• Full heat treatment and hardening to significantly increase strength

• Final surface finishing to promote smooth contact and reduce friction

Because of this meticulous process, the sear pin installs easily while seating correctly every time. Therefore, it maintains consistent fit and resists deformation even under heavy firing schedules. At the same time, it withstands high round counts without compromising alignment or performance.

Built for Strength and Long-Term Trigger Consistency

Hardened Stainless Construction for Demanding Use

Unlike softer factory pins, this hardened stainless steel sear pin maintains precise sear alignment over extended service life. Consequently, it prevents bending, deformation, and pin walk while simultaneously reducing unnecessary pivot wear. In addition, it preserves proper trigger geometry, which supports a crisp, clean, and repeatable trigger pull.

Moreover, the corrosion-resistant stainless construction withstands moisture, solvents, and frequent cleaning. As a result, the pin continues to perform reliably whether the pistol serves duty, carry, or competition roles. Ultimately, it delivers consistent performance where precision matters most.

All pins meet or exceed OEM specifications. Therefore, they provide dependable fit, strength, and function in both factory pistols and custom builds.
