Mainspring Housings - Compact Size Frames

Extreme Service Mainspring Housings for Officers ACP & Compact and other reduced length frames

Our Extreme Service Mainspring Housings (MSH from here in) are CNC machined from bar stock to consistent dimensional tolerances.

This section lists FLAT MSH for Officers ACP, Compacts, Defenders and others using a shorter length frame. Does not fit Gov't Models or Commanders, etc.

Available in blued carbon steel and stainless steel, we offer them with 25 lpi machine cut checkering, but will be bringing more options on board as machine time permits.
