There are a few big differences here:
First, powder factor is just a simple momentum formula used for the sport, when I comes to the longevity of gun parts I think kinetic energy is more useful. Since in calculating energy, velocity is squared, a lighter, faster bullets carries dramatically more energy than a slower, heavier bullet, so 9 major at 180pf and 40 at 180pf are very different, energy-wise.
Second, slide momentum in a compensated pistol is different than in a non compensated pistol as the comp delays the unlocking of the slide, dissipating energy before it cycles.
That being said, there's no hard limit to pf, and the bullet weight makes a difference. 200 rounds isn't that big a deal either way, but I keep my 115 loads under 180 for longevity of parts.
