I have varying levels of movement across all of my 1911's. My CBOB is pretty tight, my Springfield MilSpec sounds like a maraca when you shake it. But, it's my understanding that the bushing to barrel fitting is far more important than slide to frame. I fit a new bushing in my MilSpec and it's more accurate than all the others that cost far more.
We need an alert that calls Dave Waits for the definitive answer...
