Being a perspective law enforcement officer, I wonder what is the most effective caliber to use. I have always had respect for the .357 round, but recently I am starting to wonder if it is as bad-a** as some people think it is. I personly know of a man of medium build who took three rounds to the center mass, two in the lungs and one in the kidneys, at a distance of 5 yards and then got into his vehicle and drove to a neighbors house. Also seeing training videos of officer's who have used that round and ended up being shot and killed because of minimum penetration.
I would like to hear any one's opionion on what they think is prefferably the best round? My thoughts are now leaning towards nothing but a .45, but many agency's like to use a .40 cal. and now I even wonder how effective my .357 sig round is. I would think with the amount of velocity these two .357 rounds present, penitration and expansion would not be a problem when hitting a hard surface, of course .40 cal. has great ballistics, but does that round have enough ummmpppffff to do the job. I would like to hear some thoughts on this.
