Mainspring Housing, DP - Flat

 Swap out the poly mainspring housing on your STI/SV 2011-style pistol with a Dawson Precision metal mainspring housing. These mainsprings housings enable you to customize your grip to your hand as well as alter the weight and overall feel of the grip. The flat version is for shooters who want to alter the weight of the grip without impacting the overall feel.  Or, for folks who just don't want a poly MSH on their grip. These parts are CNC machined to exact tolerances from stainless steel, blue steel, or air craft aluminum (black). The stainless and blue steel models will add weight for better balance and more consistent draws. The black aluminum model does not add any weight.
