I say something I said elsewhere...
Back in the 80s the Border Patrol approved 4 rounds for use by their agents. These were the .357 Magnum with a 110 gr. jhp and a 145 gr. jhp (used by those that did not care for the muzzle blast and recoil of the former). They also approved the .38 Super with a 125 gr. or 130 gr. jhp and the .45 acp with a 185 gr. load. These loads they tested and found to give them adequate penetration and expansion for the conditions they faced.
A few years later they added a 9mm+P+ 115 gr. jhp once that load became available to them.
Four different loads that would all do what they wanted them to do given proper shot placement.
Several years after this as the size of the BP expanded they went to standardize their guns and ammo. They went with a 155 gr. jhp 40S&W. This round gave them what they had in the others.
All the rounds had about 400 ft. pds of energy at the muzzle more or less. All could penetrate barriers. All expanded as they wanted them to and all performed as desired with proper shot placement. They were careful in their selection of what ammo they recommended for the .40 as some works better than others and there are a lot of .40 loads out there.
Take your pick. What works for you in a gun that works for you. Concern yourself more with shot placement.
