I keep a .40 S&W in my nightstand, a 14 + 1 round FNX 40. I can shoot it well enough to trust my life to it, and I trust the results I will get from a 180 gr HP if I need it. My 610 revolver also shoots it very well when I'm slapping steel plates out back.
The .40 S&W is currently in a slump with the "hipsters", but so was the 10mm not to many years ago. Media hype and gun rags will spout all sorts of "*******" that proclaim the 40 S&W is "old news and has seen its day", but I challenge anyone of them to volunteer to step in front of one of the "slow & weak" .40 S&W rounds. Even wearing a ballistic vest.
Not me. I myself can tell the differences in recoil when shooting a 9mm vs a .40 s&w, and I'm pretty darn sure that difference is also felt on the other end. I'm keeping my mine close at hand in case I need to stop a criminal act and protect my life.
