  I've owned S&Ws for fifty years and never had a problem with timing yet I see "timing" questions on this forum A S&W cylinder stop engages the cylinder cut before the hammer is fully cocked (not sure about Colts). I can't figure out what parts would affect timing or what could be done to adjust it. I'm assuming "timing" means perfect chamber/barrel alignment when the firing pin hits the round.

  Revolver timing refers to the proper synchronization of the various parts that turn and lock the cylinder.
  
  On a single action, this means that drawing back the hammer causes the bolt stop to drop, the hand to rotate the cylinder, and the bolt stop to engage the cylinder again, locking it with the chamber aligned with the barrel.
  
  For double action, the same applies, but also involves the entire procedure being done by pulling the trigger.

  It's adjusted by altering any or all the parts involved in causing the cylinder locking bolt to drop out of the cylinder notch before the pawl starts to turn the cylinder. The second part of this is the requirement for cylinder lockup before the hammer begins to fall.
  On a double action revolvers several different parts are involved in single and double action operation. Timing can be complicated.
  Unlike semiautos, revolvers generally require hand fitting of internal parts. This means removing the right amount of metal from the right part(s).
  If you remove the sideplate and the hammer spring, you can observe how the parts interact to achieve single and double action operation. You can also see what would happen if one of the parts were a little too long or too short.
