Ok Jimmy is it your Rep (a salesman) or a gunsmith giving you such sage advice. My gunsmith well known by others on this sight says click it closed.
Here’s directions directly from Browning for closing a trap gun.
Upon closing your gun , let the top lever snap into position to allow the top lever spring to return the top lever mechanism to the locked position. Do not retard its action with your thumb.”
Beretta essentially mimics the same directions.
Of course if your comforted by closing the gun in your manner, carry on!
I’d bet your the only shooter on your squad using that technique.
