I found something out that makes me think about changing from 9x19mm to .45. I believe the EFMJ bullet design to be the best we can get (at least where HPs are illegal).
What stunned me is the follwowing data from Federal:
9x19mm+P 124gr EFMJ: 1120ft/sec; 345ft/lbs (467 Joule), (4" barrel)
.40 165gr EFMJ: 1050ft/sec; 405ft/lbs, (549 joule), 4" barrel
.45+P 200gr EFMJ: 1030ft/sec; 470ft/lbs (637 joule), 5" barrel
in other words: with this particular bullet type the .45 offers 36% more energy than the 9x19mm.
Does anyone know how the penetration and expansion data of these EMFJ-loads compare?
