I sent Wil my Sumatra 9mm a couple of weeks ago, and the tuning went super smooth. The gun took about a week to there (because I'm cheap), a week for him to work on the gun, and then Wil sent the gun back to me in a new gun case with 2-day shipping. Wil had good communication through the entire process and his work is amazing. If you are having trouble finding someone to tune a Sumatra (new or old), I would recommend Wil to do the work.
