When inspecting a used revolver for purchase, how do you check the timing? And is this an issue when buying a new revolver? Thanks.  |

It depends.
On most, all you can do is work the action slowly and watch that the pawl/hand carries the cylinder all the way up so that the bolt/cylinder stop catches in the cylinder before it drops the hammer. You can also cock the hammer and check the cylinder for wobble at full cock, then pull the trigger, and while holding it back check the cylinder for wobble.
Knowing whether the cylinder is lined up with the barrel is tough. You can look down the bore with a strong light while the bolt is in the cylinder notch, but this takes a better eye than I have to see if it's off .001"! You can also inspect the back of the barrel shank and forcing cone for evidence of uneven wear - bullets hitting the edge or more on one side.
Good luck. Unless you are a gunsmith and bring tools, it's a guess at best.

Hold the revolver in the right hand and turn it upside down so you can see the gap between the cylinder and the frame where the bolt engages the cylinder (it'll be upside down) Watch the cylinder lead and notch as you slowly cock the gun. You want to see the bolt drop into the middle of the lead and slide into the notch. If the bolt drops early, before the beginning of the lead, or drops late so that it misses the lead entirely and just engages the notch itself, its out of time.

[quote author=jamesjames board=gunsmithing thread=7608 post=78493 time=1336516830If the bolt drops early[/quote]....... It's a New Model Ruger! Carl PS That situation can indeed be rectified, however it takes some welding and fine file work....... |
