A couple of years ago, I put a .40 SXT into the front center chest of a pit bull that wanted a piece of me to gnaw on. I was standing on a porch, and the dog was lunging at me. (picture the angle of that shot)
The dog went straight down, yelped a couple of times, and that was it. DRT.
I'm comfortable with the .40.

I think you'll find the .40 is just about 10% less (ballistics) than the .45 ---- unless you load it with Magtech Guardian Gold 155 JHP. That round flies at 1205 fps and packs energy at 500 ft./lbs. at the muzzle. Most .45 is in the high 300's to low 400's for energy. For that matter, the Magtech Guardian Gold for the .45 packs a whallop too - the 180+P flies at 1148 fps and has muzzle energy of 540 ft. lbs. Expansion on both is awesome! I have both calibers but prefer my .45.
Ballistics aside, other's points are spot on - CONFIDENCE AND PLACEMENT. My wife does better with my 1911 than my .40 as the .40 has a snappier recoil than the 1911.

Nothing wrong with a .40SW
Here's my biased ranking of SD calibers ( I have guns chambered in all these).

A .40 is definately adequate with the right operator behind it.

I prefer 9mm or .45, but I wouldn't have a problem with .40 either considering it's the caliber used by LE in the area.

In auto pistols I think the .40 would be an acceptable alternative to the goodness that is the .45 ACP. I don't think as highly of the 9mm.

Then you're well motivated.

IIRC No 2 and No 4 are buck. It's certainly what I was thinking of when i refered to buckshot earlier.

Sorry to tell you this my friend, but it ain't true.

.40 is great for home defense. You get a round with a good amount of power in a platform that allows you a good amount of capacity in a smaller handgun. Which is pretty much why I settled on it. Rather good power and performance (check some ballistics sites, etc) in a handgun that doesn't have to be huge to achieve a large capacity of rounds.

.22, .380, .38 special, 9 mm, .40S&W, .45 ACP..... they will all work. Just remember the "three S's" Shot placement, Shot placement, Shot placement. A good hit with a standard velocity .38 is a lot better than string of loud misses from a hi cap .40 anything! A handgun with a full size grip and a 4" or 5" barrel is easier to hit with than someting smaller. Only hits count.

Hopefully the enemy only knows 90 percent of the Marines -the last 10 percent the enemy does't know is what has defeated the Marines enemies time and time again-as proven by history!

The 40 round is what I use for HD needs. Higher capacity then a 45 and more punch then the 9mm IMHO so a perfect round.
