Famed Texas Ranger Joaquin Jackson wrote in one of his books that he gave up on the .45 FMJ and switched over to hollow-points as he thought they had better stopping power against bad guys after he shot a bad guy with an FMJ and the bad guy kept charging.
One of my buddies has a Glock 30 in .45 ACP and swears by it. Will have to check it out. Love my Glock 26 though.
