Refitted today.
I did not chill or heat anything. The bushing itself, i could push it into the slide 1/2 way just by hand. A few light taps with a soft face hammer and it was home.
The cross pin channel is a little tighter than stock, but not too bad. I thought about running a drill bit through but decided to insert the pin first. It was a good tight fit, so i left it alone.
Barrel install into the slide is a little tight. I ended up tapping the under side of the barrel down with my soft face hammer and it popped right in.
Taking the barrel out is a little tight too. I hope over time this will wear in.
I will take it out to the range tomorrow during lunch to see what's what.
