You have the same "worries" the owner of any other S&W revolver has. Keep the gun as clean as you can. Hold your amount of really fast double-action shooting to a minimum. Check your weapon frequently for any signs of disrepair, viz. excessive cylinder- and yoke-endshake, timing problems, straight extractor rod, etc. Anyone should do that with any revolver. In other words, just do the normal things.

Others may disagree but I don't consider the 19.0/2400 load a "medium" power 44 Magnum. That is a pretty sturdy load and should approach 1300 FPS in a 6-inch gun. Nothing to sneeze at.
