Can't speak for the 535 specifically but I don't think it will be an issue. The more I shoot my Mossbergs (500 and 930), or any shotgun, the smoother and more reliable it gets.
Aside from wear on the finish, i can't say I've noticed any detrimental wear on any of my guns, some of which have many many 1000's of rounds through them.
Keep it lubed and it should keep working indefinitely. I expect my guns to outlive me.
