✅ 1911 Main Spring Housing Pin – Blued
Our Mainspring Housing Pin provide a Precision Fit • Hardened Strength • Long Service Life
The 1911 Main Spring Housing Pin – Blued delivers a precision-fit replacement for worn or damaged factory pins. Built from high-grade steel and finished in durable black oxide, this hardened 1911 mainspring housing pin restores proper housing retention, improves frame alignment, and ensures long-term reliability in duty, carry, and competition pistols.
When a mainspring housing pin wears or loosens, it causes unwanted movement and inconsistent performance. This blued 1911 mainspring housing pin eliminates those problems by providing a tight, stable, and long-lasting fit.
✅ Precision Swiss CNC Manufacturing
Each 1911 blued mainspring housing pin begins as high-grade steel and is machined on high-end Swiss CNC screw machines for exact dimensional control. After machining, every pin receives:
• Centerless grinding for precise diameter
• Full heat treatment and hardening
• Final surface finishing for flawless installation
The result is a pin that installs clean, seats securely, and resists wear under recoil and extended use.
