Default Revolver Lockup Tolerance

A local gun shop/range (that has not demonstrated competence with revolvers) has informed me that two of my revolvers are "out of time" and therefore unsafe to shoot. I asked them to show me. This is what they did...
- Cock the revolver.
- With the hammer back, attempt to turn the cylinder right and left.
- There is some noticeable wiggle. Not much, but you can see/feel the wiggle. I measure the wiggle at approximately 0.5 mm (holding ruler next to cylinder as I wiggle it).

What is the proper term for this wiggle?
What is the acceptable tolerance for this wiggle?

Thanks,
--Joe.

PS: One of the revolvers is a .38 M&P from 1920. Caliber marked on barrel is "38 S&W Special CTG". Clerk at gun shop told me that this is not the same our current .38 Special, but an older fatter obsolete round - he was clearly confusing this with .38 S&W. So now I don't believe anything they say.
