People, of course the .40 S(hort) & W(eak) is better. We all know that any cartridge over 100 years old can no longer be relied on to kill it's intended target. Why the 30-30 and the 45-70 are so old that they don't even qualify as mouse guns anymore. So, the 9mm and the .45 acp both being past the century mark will have absolutely no effect on targets. They just bounce off.
Heck, I hear they all bounce off, including the 10mm, which uses a .30 Remington case cut in half (why cut anything in half?). My personal preference is a "40" - a phased plasma rifle in the 40-watt range.
