Nighthawk Custom 1 Piece 1911 Government, Commander Mainspring Housing and Magwell 25 LPI Checkering Steel Blue

Nighthawk Custom's 1-piece Mainspring Housing / Magwell is the strongest most robust part of its kind anywhere. It sets the standard for what this part should be. It starts out life as a solid 2 1/4" block of steel. It's then fully machined and checkered to exacting tolerances. The bottom of the mag well is rounded to reduce the print thru clothing when wearing your firearm concealed. The checkering is 25 lpi to provide a more positive grip.
