2011 Mainspring Housing Pin – With Magwell | Stainless Steel
The 2011 Mainspring Housing Pin – With Magwell provides a precise, dependable replacement for 2011 pistols equipped with a magwell. From the start, this pin uses high-grade stainless steel and exact tolerances to restore a secure fit, smooth assembly, and consistent performance.
Over time, factory pins inevitably wear. As they loosen, bend, or begin to walk out under recoil, overall function suffers. Consequently, reliability declines and alignment issues appear. This stainless steel replacement solves those problems by delivering a correctly sized, hardened, and long-lasting design built for serious use.
Precision Swiss CNC Manufacturing
Exact Fit From Start to Finish
To begin with, this pin starts as premium stainless steel. Skilled machinists then shape it on high-end Swiss CNC machines to achieve precise dimensions. After machining, each pin goes through multiple finishing steps to ensure accuracy and durability.
First, centerless grinding brings the diameter to an exact specification. Next, full heat treatment increases strength and wear resistance. Finally, the pin receives a smooth finish to promote clean contact during installation.
As a result, the pin installs easily, locks in place securely, and continues to perform through extended use.
Built for Strength and Long-Term Reliability
Designed to Hold Under Recoil
Unlike softer factory pins, this 2011 mainspring housing pin stays tight under recoil. Because of its hardened stainless steel construction, it resists bending and deformation even during hard use. In addition, it prevents pin walk during firing, which helps maintain proper frame and housing alignment.
Furthermore, every pin meets or exceeds factory specifications. Therefore, it performs equally well in duty pistols, competition guns, and custom builds where reliability matters most.
