I already have a .357 and a 9mm . What's the difference between the .40 and the .45 in a semi-auto ? Looking to add another caliber for now and possibly the other caliber at a later date . Thanks

The thing is, unless you hit the central nervous system or the spinal cord, you really never know how your assailant is going to react to being hit. There are just too many variables to make a cut and dried statement about stopping someone or causing them to collapse. This is why proper training will include the concept of firing until the threat is eliminated (this means ceases). Now if there are multiple attackers, this concept is the best argument for "high capacity magazines". Misses, non-stopping hits, BG's who can take a lot of punishment.... all scream for having enough ammunition in your firearm to give you a chance to survive.

But the fact remains that you are not going to know whether or not your chosen caliber and load is going to do the job in an instant case until you have to call upon it to save your skin.
Yea, there is "no standard" in BG's, but most of them are probably scared silly, just desperate when they break into homes. Racking a shotgun or a belly peppered with rat-shot will send them scurrying like the rat they are. I bet the guy that got the belly full of rat-shot had no idea of caliber or round, just that he had been shot and wanted only to get the hell out of there.

There is always a 12ga automatic with slugs or 00 if your looking to transfer foot-pounds of energy into the BG.
