SAAMI maximum chamber pressures for standard pressure 9mm and for .40 S&W are the same. Of course, simply comparing average maximum chamber pressures across calibers doesn't necessarily tell you anything.
9mm vs. .40 longevity

How much less is the lifespan of a modern .40 (not .45) pistol compared to a modern 9mm?
There's the Glock 17 in 9mm and the Glock 22 in .40, for example. S&W makes the M&P in both 9mm and .40 the last I checked. I think Sig makes both polymer and steel/aluminum pistols in .40. There was the CZ 75 in .40 but the don't make them anymore. I don't recall is Springfield makes their polymer guns in .40 anymore.
