The EGW GI Arched Mainspring Housing is the removable rear-frame backstrap panel that houses the mainspring on a Commander-frame 1911, made by EGW (brand part no. 11441). Its arched profile changes the grip angle/palm-swell feel compared to a flat housing, and it adds a lanyard loop for attaching a retention lanyard. It carries a blued finish to match traditional carbon-steel 1911 controls.

Frequently Asked Questions

What is the difference between arched and flat housings? An arched housing changes the grip angle and palm-swell feel in the shooter’s hand compared to a flat housing, which is mostly a matter of personal preference and hand fit.
