the owner is aware of it. The momentum of the cylinder will often "carry" it on around until the cylinder bolt stops it. However, if you ever slowly cock the hammer (either SA or DA) then the hand is worn too short to fully rotate the cylinder around.
To check for this condition, with an empty gun of course, slowly cock the hammer, or work the DA trigger pull, while putting some friction against the side of the cylinder with a finger of your non firing hand. once you think you've rotated the cylinder all the way, slowly grab the cylinder with your nonfiring thumb and finger, and see if you can rotate it any further towards full lock.
Sometimes, this condition is a simple fix, done by "peening" the end of the cylinder hand with a hammer, on an anvil, starting about 1/4" from the point, and working towards the point. Sometimes, replacement of the hand is required. Sometimes, replacement of the cylinder bolt is also required. Sometimes (pretty rarely) the bolt notches in the sides of the cylinder are so worn that the entire cylinder needs to be replaced. Dont even THINK about Tig welding up the notches and recutting them, except perhaps on a .22lr, or a 5 shot model (where the bolt notches fall between the chambers, instead of at the thinnest point, as it is on the 6 shot models.
