1911 Mainspring Housing Pin – Stainless Steel – 5 Pack
Precision Replacement Pins for Reliable 1911 Performance
To begin with, the 1911 Stainless Steel Mainspring Housing Pin – 5 Pack provides a simple yet critical upgrade for maintaining proper fit, alignment, and long‑term reliability in any 1911 pistol. Whether you are replacing worn factory pins, servicing multiple firearms, or stocking parts for future builds, these pins deliver consistent performance and dependable strength.
Moreover, each pin is manufactured from high‑grade stainless steel using precision Swiss CNC screw machines. As a result, every pin meets exact dimensional standards while providing a clean, accurate fit across all standard 1911 frames. Consequently, installation remains quick and trouble‑free with no fitting required.
Precision Manufacturing for Consistent Fit
Swiss CNC Machining and Centerless Grinding
First and foremost, Swiss CNC machining ensures tight tolerances and repeatable accuracy from pin to pin. In addition, each mainspring housing pin is centerless‑ground after machining. Because of this process, the pins install smoothly, align correctly, and maintain consistent engagement over time.
Furthermore, this precise machining minimizes play and reduces unnecessary wear on surrounding components. As a result, your 1911 maintains proper function and reliable retention shot after shot.
Heat Treated for Strength and Longevity
Built to Withstand Recoil and Repeated Use
After machining, every pin undergoes heat treating and hardening. Consequently, structural strength increases significantly while resistance to deformation improves. Over time, and even under heavy use, these pins hold their shape and retain proper fit.
Additionally, this hardened construction extends service life, making these pins ideal for duty pistols, competition firearms, and high‑round‑count range guns alike.
Corrosion‑Resistant Stainless Steel Finish
Durable Protection in Any Environment
Just as important, the natural stainless steel finish provides excellent resistance to corrosion, moisture, and surface wear. Therefore, these pins perform reliably in humid conditions, during extended carry, or after frequent cleaning. At the same time, the clean stainless appearance maintains a professional, factory‑correct look.
5‑Pack Value for Builders and Gunsmiths
Ready for Installation
Because this set includes five identical pins, it offers outstanding value for gunsmiths, custom builders, and shooters maintaining multiple 1911 pistols. All pins meet or exceed original factory specifications and arrive ready to install. As a result, you can simply drop them in and secure them without additional fitting or modification.
