ADN53XX serial no#
Also there is no M or 2 so that tells me that there is no MOD or L frame improvement mod.
The recall was from an issue involving only a few guns and with a certain brand of 357 Mag ammo.
The primer metal would flow back into the firing pin hole and tie up the action. S&W's fix is to replace the firing pin bushing.
If you are not experiencing that problem then I would not worry about it.
