Common Problems/Repairs

  • Subject revolver has rotational play, end shake, and times up slow (what these mean, and how to correct them)
  • Correcting the end shake, it is not easy, but this is how you do it
  • How to correct the rotational slop
  • Ruger® springs are designed for Ruger®s, stay away from aftermarket springs other than Wolfe
  • Be careful of trigger jobs, since most Ruger® hammer/sear engagement are negative. They must be positive if you do a trigger job. If you do not understand positive and negative engagement angles, get the Trigger Course
  • Correcting the timing issue, stretching the point

If you noticed how often the terms “explanation” and “demonstration” are used, you may be getting some idea of why this course is necessary for any Ruger® single action revolver owner, or someone who intends to be.
