I hate to introduce myself here as the fact police, but....
That post is all good and well if you are using a .22lr RIFLE for SD. If you're using a pistol, you can take those pretty numbers and throw them away. CCI stingers fired out of a 3" pistol bbl will pop out going about 970 FPS. (32gr x 970 x 970)/ 450400 = 67 ft lbs of energy. S&B .32 acp loads are advertised as 190 ft/lbs of energy out of a 4" bbl, plus a bigger hole, plus a slug twice the size of the .22lr.
If all you have for SD is .22lr, then rock it. You DO need to understand the capabilities and drawbacks of the round. Advertising that CCI stingers or .22 mags are just as good as .32 acp and .380 is some pretty misleading information. Of course, if it's coming out of an 18" bbl and the pistol cartridges are coming out of a 4" bbl, then it is indeed true. Make sure your comparison is apples to apples.
I would rather have 9mm, but I would use it
I have a mark III, and have told several people, several times. I would rather have it with me if I needed it than almost anything else. Good in most situations, without a lot of downsides. But on to the ammo debate.
At 7 yards I could put all ten rounds into a paper plate in a little over a second.
Think buckshot. Little holes, and a lot of them. NO one says buckshot won't stop someone,
I think people over estimate big rounds, and under estimate little rounds.
22 stinger hits harder than a 32 auto, with a smaller hole.

22 mag hits harder than 380, and even 38 special +p. but again, smaller hole.

And if people say it's about caliber size.... why do people have 223 rifles? Bullet speed is important in causing trauma, trauma causes shock.
I think any gun is a good defense in the right hands. Train well, find what works. go with it.
