Nice P220 you got there and congrats.
Looks to me like like it is barely broken in.
Shoot it often as you can afford and you will love it. Just be sure to keep the frame rails well lubed and a light coat of lube on the barrel exterior in addition to other recommended lube points. I would however change the recoil spring sometime in the near future since it is used. Recoil spring should be ideally changed every 3000 - 5000 rounds.
