The SJC Home Build Open kit has the only home installable match grade barrel truly suitable for major and minor 9mm loads. This 9mm SJC barrel starts as a KKM match grade barrel so you get the same quality as all of the SJC built world chanpionship pistols, but lose the time and expense of the in house gun smith fitting. The 9mm SJC barrel still has the proper chamber, throating, and threads to obtain a quality open builds at home. Trying to use any other drop in fit barrel for major 9mm loads gives the brass case excessive room for expansion. These other barrels do not have true fully supported chambers. This can cause case ruptures and sticky extraction issues with major 9mm loads and these issues are not condusive to a reliable pistol or competition wins. Addtionally, the SJC home build open kit removes the need to diagnose and tune ejection systems of the open Glock. By changing from the c-more mount to the cmore sideways mount ejection patterns are no longer of any consequence. No more stove pipe jams. The SJC home build open kit also comes with the guide rod and recoil springs suitable to use both major and minor loads.
