The Python is a target grade revolver, with lockwork hand-fitted like a fine watch. Think Porsche or Ferrari. If you care for it, you can shoot it indefinitely before it gets "out of time". However, I was taught to always draw back the cylinder latch before closing the cylinder, and fire it single action only, unless an emergency. So no slammin' it shut, D.A. speed work, or other rough treatment. Keep it squeaky clean and lubed. I have a "shooter" mfg. 1970 that I have owned 25 years and run many, many, boxes of factory .357's through, with no apparent wear. If you are the type who takes care of his equipment and has pride of ownership, you will be well pleased. On the other hand, if you drive a beat-to-hell Yugo with a rusty 870 Remington rattling around in the trunk, buy something else. It ain't a good fit.
