What are all the possible causes of disconnector click? Is it binding in the tunnel? Or binding in the clearance cut-out in the bottom of the slide? Or can there be other causes? What are the fixes for these problems? How does staking the tunnel fix this? How does deepening the disconnector notch affect disconnector click? I read Metalsmith's post where he recommends the Infinity disconnector, but I am wondering if there are additional ways for binding to occur.
