1911 MainSpring Housing Pin – Blued

Restore Secure Retention, Proper Alignment, and Lasting Reliability

The 1911 MainSpring Housing Pin – Blued offers a precision-fit replacement for worn, loose, or damaged factory pins. Furthermore, it is manufactured from high-grade steel and finished with a durable black oxide coating. Consequently, this hardened pin not only restores proper mainspring housing retention but also improves frame alignment. As a result, your 1911 maintains consistent performance across duty, carry, and competition use.

Over time, factory mainspring housing pins often wear or loosen. Consequently, unwanted movement develops, alignment suffers, and overall reliability declines. However, by installing this blued 1911 mainspring housing pin, you immediately correct those issues. In turn, it eliminates housing shift and restores predictable, repeatable performance, ensuring your pistol operates smoothly and reliably.

Precision Swiss CNC Manufacturing

Each blued 1911 mainspring housing pin begins as premium steel stock and is then precisely machined on advanced Swiss CNC screw machines. Moreover, after machining, every pin undergoes a controlled finishing process that includes:

• Centerless grinding for precise diameter accuracy

• Full heat treatment and hardening for increased strength

• Final surface finishing to ensure smooth, trouble-free installation

Because of this meticulous process, the pin installs cleanly, seats securely, and resists wear under recoil and extended use. Therefore, fit remains consistent even after thousands of firing cycles. In addition, this precision ensures that each pin performs exactly as intended, shot after shot.

Built for Strength and Long-Term Reliability

Unlike softer factory pins, this hardened steel mainspring housing pin resists bending, deformation, and pin walk. Consequently, it maintains proper housing alignment and prevents movement under recoil. At the same time, it supports consistent ignition and preserves stable internal geometry.

Additionally, this blued pin withstands high-round-count use without loosening or wearing prematurely. As a result, it not only restores immediate performance but also helps extend the service life of your frame and internal components. In short, it provides both short-term reliability and long-term durability.

Furthermore, all pins meet or exceed manufacturer specifications, which guarantees dependable fit, strength, and consistent performance under the most demanding conditions.
