While a .40 may be legal for hunting elk I would step up some in power to do so cleanly. I haven't looked at the energy levels that a .40 S&W has but for it to be legal it needs to have 500 foot pounds of energy at 100 yards for elk.
I have killed a few elk with pistols. A .357 mag, .44 mag revolvers, 7-30 Waters, and .357 Herrett out of a Thompson Center Contender.
The closest shot was on a cow at 20 yards and the furthest was a 150 yard shot on a raghorn bull in Colorado.
