Uneven Cylinder Lockup

Should the lock up on each chamber of a revolver be inconsistent? I checked out a new revolver today. With the hammer pulled back on each cylinder, chambers 1 and 2 were very tight, with little rotational play. Chambers 3 and 4 had 1.5x as much play, and 5 and 6 had 2x as much play. The inconsistency was very noticeable. Why does this happen?

Welcome to the board.

There are too many possibilities to give a definite answer. Burrs on the freshly machined parts comes to mind as one possibility.

Your question should be does this matter, not why does this happen.

The hammer pulled back into single action is not considered lock up. Lock up can be checked by pulling the trigger, letting the hammer fall, and holding the trigger to the rear. This can be done by either single or double action. You can then check for rotational play while still holding the trigger back. Some revolvers are tight on lockup. Most will have a bit of rotational play. Reportedly the bullet passing from the cylinder to the forcing cone on the barrel aligns the two. Not an issue unless the gun is spitting lead. Of the ten revolvers I own, I think two have a solid lockup. Lockup is controlled by a relationship between the hand and the ejector star or ratchet.

If the gun is spitting lead it is a job for a qualified gunsmith. He will use a range rod to check alignment issues and then address the ejector ratchet that corresponds to the chamber he is checking.

No need to worry about a little play.
