>I am actually tempted to buy hotter loads to see just what my 92FS can take
Winchester Service grade is a 115 gr going at 1300 fps, by far the hottest "range" load and it's only ~25 cents. 
Doesn't say it's +P, but Federal's 115gr +P+ load is the same velocity, having shot both Federal's way hotter but Winchester Service Grade is hotter than any range load I've seen.
