TMC Sear Pin – Carbon Steel – Blued – Hardened

Sear Pin – Carbon Steel | Blued

Restore Precise Sear Alignment While Preserving a Classic Blued Finish

The 1911 Sear Pin – Carbon Steel, Blued delivers a precision-machined replacement that, first and foremost, restores correct sear alignment and smooth, repeatable trigger movement. Moreover, it reinforces long-term reliability while maintaining the traditional blued appearance preferred for classic and duty-style pistols. Additionally, because it is manufactured from high-strength carbon steel and fully heat treated, this sear pin provides the durability, wear resistance, and dimensional accuracy demanded by serious shooters and professional gunsmiths.

Over time, factory sear pins can soften or wear. Consequently, alignment shifts, trigger feel becomes inconsistent, and internal components experience accelerated wear. However, this hardened carbon steel replacement directly addresses those issues. By combining precise tolerances with robust material strength, it restores stability, predictability, and confidence in your trigger system.

Precision Swiss CNC Manufacturing

Exact Tolerances for Reliable Fit and Smooth Function

Each sear pin starts as premium carbon steel and is then machined on advanced Swiss CNC screw machines to ensure precise dimensional control. Furthermore, after machining, every pin completes a controlled finishing process that includes:

• Centerless grinding for exact diameter accuracy

• Full heat treatment and hardening for increased strength

• Final bluing for corrosion protection and a uniform appearance

Because of this detailed process, the pin installs easily and seats correctly. Therefore, it maintains consistent fit while resisting bending and deformation under heavy firing schedules. At the same time, it preserves reliable operation at high round counts.

Built for Strength and Consistent Trigger Performance

Hardened Carbon Steel for Long-Term Reliability

Unlike softer factory pins, this hardened carbon steel sear pin maintains precise sear alignment shot after shot. Consequently, it minimizes pin walk, reduces pivot wear, and preserves proper trigger geometry. In addition, the blued finish provides traditional corrosion resistance while matching classic 1911 aesthetics.

Moreover, the strength of heat-treated carbon steel supports demanding applications such as duty use, training, and competition. As a result, trigger feel remains crisp, predictable, and consistent throughout extended service life.

All pins meet or exceed OEM specifications. Therefore, they deliver dependable fit and function in both factory pistols and custom 1911 builds.
