This is more or less just an FYI post for anyone looking for the bushing from Sam. If anyone posts on this site looking for it, point them to this thread please.
Ruger Mark III 22/45 has an annoying design flaw called a "Magazine Disconnect", which iwhere the magazine only partly drops out when ejected and it doesn't insert (or stay in) very well when inserted into the gun. The solution for both problems is to remove the magazine disconnect. Below is a photo of the bushing, a vide on how to do it, and a link where to get it at.
