2011 Mainspring Housing Pin – Magwell | Blued

2011 Mainspring Housing Pin – With Magwell | Blued

Precision Fit, Hardened Strength, and Long-Term Reliability

The 2011 Mainspring Housing Pin – With Magwell delivers a precise, dependable replacement for 2011 pistols equipped with a magwell. Because this pin uses high‑grade carbon tool steel and exact tolerances, it restores secure fit, smooth assembly, and consistent performance.

Over time, factory pins wear. Consequently, they loosen, bend, or begin to walk under recoil. When that happens, reliability suffers. Therefore, this blued replacement pin solves the issue with a strong, correctly sized design built for serious use.

Precision Manufacturing for a Secure Fit

Swiss CNC Machined Accuracy

This pin begins as premium carbon tool steel. Skilled machinists then shape it on Swiss CNC machines for precise sizing. After machining, each pin receives centerless grinding, full heat treatment, and final finishing. As a result, installation stays smooth while retention remains tight.

Built for Strength and Reliability

Hardened for Hard Use

Unlike soft factory pins, this mainspring housing pin resists deformation. Moreover, it stays locked in place under recoil. Therefore, it prevents pin walk, maintains proper alignment, and supports reliable cycling during extended firing.
