Sear Pin – Ambidextrous Safety – Carbon Steel, Blued
Ensure Proper Ambi Safety Clearance and Consistent Trigger Performance
The Ambidextrous Safety Sear Pin – Carbon Steel, Blued delivers a precision-engineered replacement designed specifically for 1911 pistols equipped with ambidextrous thumb safeties. First and foremost, this sear pin features a flat-cut right side, which provides proper clearance for ambi safety levers. As a result, the safety engages and disengages smoothly without interference, drag, or binding.
Moreover, this pin is manufactured from high-grade carbon steel and fully heat treated to restore tight tolerances, clean trigger movement, and dependable long-term performance. Consequently, both duty and competition pistols benefit from improved reliability and consistent operation.
Precision Swiss CNC Manufacturing
Exact Tolerances for Reliable Fit and Function
Each ambidextrous safety sear pin begins as premium carbon 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 accuracy
-
Full heat treatment and hardening for increased strength
-
Black oxide blued finishing for corrosion resistance and reduced glare
-
Final surface finishing to promote smooth operation and wear resistance
Because of this meticulous manufacturing process, the pin installs cleanly, seats securely, and maintains proper fit through extended firing cycles. Therefore, reliability remains consistent even under high round counts.
Designed Specifically for Ambidextrous Safeties
Flat-Cut Profile for Proper Clearance
Unlike standard sear pins, this ambidextrous model incorporates a flat-cut right side. Consequently, it clears ambi safety levers without interference. At the same time, this design:
-
Prevents binding and unwanted drag
-
Maintains smooth, positive safety engagement
-
Preserves clean, repeatable trigger movement
As a result, pistols equipped with ambidextrous controls retain proper safety function without sacrificing trigger feel or consistency.
Built for Strength and Trigger Consistency
Hardened Carbon Steel for Demanding Use
Soft factory sear pins often bend, walk, or wear prematurely. In contrast, this hardened carbon steel sear pin resists deformation and peening under recoil. Consequently, it maintains precise sear alignment and preserves correct trigger geometry.
Additionally, the hardened construction protects high-quality trigger jobs while supporting consistent performance through extended shooting sessions. As a result, the pin delivers long-term reliability in pistols that see frequent or demanding use.
All pins meet or exceed OEM specifications. Therefore, they perform reliably in factory pistols, custom builds, and competition guns alike.
