I have been lucky that not very many guns have needed the new bushings.I could have easily spent that much there today, but I'm still recouping from my Holiday shopping spree. To fully cajunize the other 3 guns I would need race hammers and disconnectors. That's almost $400 right there. I'm also really liking these triggers with the overtravel adjustment, which I have two that currently are rocking the 97 style thick trigger, because at the time those triggers were only like $22 each and were an improvement over the stock black re-curve trigger. So to do triggers I would add another $70-$84. I'm also interested in doing the upgraded barrel bushings on three guns, there goes another $180.
