The K frames are great to shoot.
Enjoy that 4" 1980s beauty
I own a 3" 66-2 that sees some range time about once a month and only gets fed 158gr LSWC ammo loaded in 357 cases.
The Speer Gold Dot 357 is my personal defense/carry ammo most of the time
The linked Hogue rubber grips with S&W logo are comfortable at the range
