Can excessive endshake cause binding?
Curious to know if excessive endshake on a S&W revolver can cause significant binding, hindering or altogether stopping tigger pull?
If so, what's the mechanical explanation?

When you pull the trigger, the hand pushes the cylinder forward as well as rotating it. If there is enough endshake, (doesn't take much), the front of the cylinder will rub on the back of the barrel. This can cause anything from a harder trigger pull to total lockup. If shooting lead bullets, the lead can build up in a small b/c gap (caused by endshake) and tie up the gun too.

Endshake is the enemy of a revolver.

The hand isn't on a fixed plane?

No. It retracts at the bottom of the stroke, then goes outward as it moves up. It can move forward more than the depth of the space between the ratchets. Usually, the center pin is pushing the cylinder forward all the time, too.

When it becomes excessive, end shake can tie up a revolver.
