Dawson Precision ZM Arched Main Spring Housing – Black Aluminum – CNC machined to exact tolerances from aluminum with silver or black anodized finish. 20 LPI checkering provides a better grip for more control and adds that custom look. Adds almost no weight over factory polymer Mainspring Housing. Fits all full size STI 2011 with polymer grips, requires little effort to install.

  • Small grip requires blending grip to mainspring housing, not a problem use the small Mainspring Housing as a guide and it’s pretty easy.
  • Does not work with the Staccato Gen 2 Grips.
