I have to completely disagree with this.
A brilliant LCI is like the ones used by Glock or Walther, which simply use the extractor position to provide visible and tactile indication of a loaded chamber, without having to add large parts and complexity to the pistol design.
Even the hole used by S&W and others is a more elegant design, though it provides no tactile feedback.
That said, one should never depend on a LCI to determine the whether a gun is loaded.
