When selecting an ammo to use and practice with, many people end up choosing between 9mm, .40 S&W, and .45 ACP. My journey through these three calibers was relatively short, and the changes were based on convenience rather than logically calculated decisions. Nowadays I shoot 9mm primarily, which is a choice many people get behind every year. But lately I have looking at and considering another caliber switch. Perhaps not in terms of my primary caliber, but at least in carry.
Many people like to think they are doing sufficient research to find the PERFECT carry round for their firearms. Realistically and simply, there is a marginal difference between the performance of premium and generic ammunition. Of course this depends on what you get, but older designs like Winchester white box JHP ammo seems to perform really well and consistently in most testing. Of course it isn't pretty, but penetration is dominant for those of us in the real world with our priorities straight and logical.
Shorter barrels generally tend to vent more pressure, making it harder for rounds to achieve maximum potential velocity. This in turn can affect your terminal results. Such things like failures to expand are the primary concern when considering ammo to carry in any firearm.
