Replace your factory installed plastic main spring housing or upgrade your metal serrated main spring housing with our 20 LPI checkered main spring housing. The 20 LPI checkering will give a non slip, non shift grip. Available in stainless or blue.

  1. Not as expected!!

    I ordered the arched, checkered mainspring housing for installation on a Kimber 1911. The cast quality was poor to the point where it could not be salvaged through Emory board or polishing compound on the sides that show. Needless to say that it cannot be used on any of my quality (or even non-high quality 1911) firearms. Highly disappointed.

  2. Quality Product

    I used this to replace the msh on a GSG 1911-22. Snug fit and easy to install. Matched the color of the rest of the gun nicely. Great checkering. Feels like a really quality piece. Very happy.
