We can agree to disagree on "stopping" power of handguns but I say if a modern hot 9mm hollowpoint to the chest won't stop a gunfight a 45 wouldn't either. Now with ball ammo BOTH are shitty stoppers but the 45 has a definite edge. If I had to carry a handgun using only ball ammo it would be a 45.
BTW the Nato 124 gr load is right next to a duplicate load to the 125 grain 357 load. I know everyone here is big bore happy but even most of them will admit the 357 WILL stop a gunfight fast. As you know there are 4 load standards for the 9mm Saami, +P, +P+, and Nato. The Nato load is a 124 grain bullet at 1350 fps. It is also loaded to 42,000 PSI if I remember correctly. No American Manufacturer will load to that pressure. The top pressure loaded in the USA is +P+ which is plenty hot and will get the bullet out plenty fast enough. If the 9mm was available with Nato pressure loadings and a modern hollowpoint it would be my personal favorite. As it is I just carry the Corbon 115 gr but I feel real good about that round doing its part if I do mine.
A word of advice about hot powder +P loads in your 9 x 19 handgun: some handguns are not built for +P loads (consult your user's manual for your handgun).
With handgun loads your hollowpoint will not expand about 50% of the time. This is what they have found in numerous shootings where handguns have been used as handgun bullet velocites are so low.
