He was a loudmouthed self proclaimed authority. Try Marshall and Sanow. They have catalogued every law enforcement shooting for many years and last I heard the 357 was at the top of the heap. It was barely above the rest. The modern 9mm cartridge was ranked very high
About all U.S. forces prefer the 1911 .45 handgun over the Beretta 9 x 19. There was a rally to dump the 9 x 19 and go back to the .45 ACP because .45 ACP has much more stopping power. 230 grain bullet versus 135 grain bullet. I think they didn't do it because our N.A.T.O. allies use handguns with the 9 x 19 round.
