Pjames,
Congrats on your purchase...used guns are always iffy, but have mostly worked out well for me. Take it down, clean it thoroughly, hold it firmly (for practice, a shooting glove is a nice addition to prevent "bite" when multiple rounds are fired. Allow the pistol to cool as tolerances are tight. Use premium ammo (Gold Dot 124 or Federal HST seem to be consensus, or Lawman 124 for practice). Shoot well, shoot often, and welcome to the forum and to the Rohrbaugh experience.
