2011 Mainspring Housing Pin – No Magwell | Stainless Steel

2011 Mainspring Housing Pin – No Magwell

Stainless Steel Precision for Secure Fit and Long‑Term Reliability

To begin with, the 2011 Mainspring Housing Pin – No Magwell provides a precise replacement solution for 2011 pistols configured without a magwell. Because proper pin fit directly affects frame alignment and component retention, this pin restores secure engagement, smooth assembly, and consistent performance.

Over time, factory pins inevitably wear. Consequently, they can loosen, bend, or walk under recoil, which quickly compromises reliability. For that reason, this stainless steel mainspring housing pin corrects those issues by delivering exact sizing, hardened strength, and dependable long‑term durability.

Precision Swiss CNC Manufacturing

Exact Dimensions from Start to Finish

First and foremost, this pin begins as premium stainless steel. Then, skilled machinists produce it on high‑end Swiss CNC screw machines to maintain precise diameter and consistent length. After machining, each pin undergoes centerless grinding to refine the fit even further.

Finally, full heat treatment increases strength and wear resistance. As a result, the pin installs cleanly, locks firmly in place, and continues to perform reliably through heavy use.
