I received my shipping notification. The R8 will likely arrive Saturday. Unfortunately I won't be able to pick it up until Monday as I'm very much looking forward to shooting it.

As for the Wolff spring kit, I always order one for revolvers if a kit is available. I like my DA pull to be under 10 lbs. I imagine the performance center mainspring will be fine but I may play with the rebound spring a little to see what impact it has (good or bad). It's also a good way to learn more about a revolver. I've only worked on Rugers to date.
