A proprietary BevelBlock™ fitting block of extra material on the front ledge of the mainspring housing forms a seamless butt joint with the frame, deep into the frame’s magazine well. Cutting the bevel to the rear on a standard mainspring leaves a gap between the frame and mainspring housing that is prone to damage and snagging on magazines when they are inserted in the pistol; the Chen MaxBevel™ Mainspring Housing completely eliminates this problem.
The overall dimensions were also carefully spec’d to deliver a nice snug fit in most 1911 frames without excessive material removal. Perfect for carry applications to greatly increase the magwell opening with no extra bulk.
Requires one simple machine cut for installation before cutting bevel. Complete, detailed instructions on how to do a world class magazine well bevel job included.
Mainspring housings are flat and smooth, available in carbon and stainless steel. Fully machined from certified barstock. Made in USA.
Unique design allows magazine well bevel to be seamlessly cut to the rear, right into the mainspring housing with no gaps.
The Chen MaxBevel™ Mainspring Housing for single stack 1911’s allows the custom gunsmith to seamlessly cut the bevel of the magwell back into the mainspring housing, allowing a much larger magwell opening without an add on magwell.
This modification allows shooters to hit the sweet spot at the rear of the magwell during combat reloads, as taught by prominent shooting instructors.
Should be required for every 1911
