Yes, peak operating pressure, which hasn't dropped all that much by the time the bullet clears the muzzle gap on a revolver.

"9mm has a high peak pressure because it has to do what something like .38 does with a much smaller case."

The 9mm does NOT do what the .38 Special does.

The ballistics are NOT similar.

9mm ballistics are far closer to .357 Magnum ballistics.
