  Not much shock value, low speed
  Shooting has to be accurate
  To figure out, which is a better option, let's take a look at the 9mm vs. .22 reviews and see what they can be used for:
  According to a study about shootings in Boston, bullet size affected the death rate from shooting wounds. .22 compared to 9mm was less lethal. But to stop an attacker, you need to strike something critical and cause a good deal of pain. 22LR vs. 9 mm ballistics gel tests show that, unlike a 9mm round, the .22 bullet often fails to penetrate. At least not deep enough to hit a vital organ. Plus, the bullet's hollow points expand very little. And of course, the .22LR is a lot more comfortable to shoot thanks to the low noise. So you can fire your gun rapidly and accurately. On the other hand 9mm, designed for combat, is much more powerful. It penetrates deep into ballistic gel. Plus, 9mm guns are very accurate. You can fit this cartridge into a Glock 43X or 9mm 1911 magazines. Some top-rated small pocket pistols like Kimber Micro will also work fine with this cartridge. Either way, you've got an effective gun for home defence.
  When talking about .22LR vs. 9mm for the hunt, then the former is a winner in this regard. That is because the 9mm cartridge is mostly for handguns. But you can fit the .22LR ammo in some of the best hunting rifles on the market, like the .300 or 308 rifle. The problem with the 9mm round is that it will damage the meat of your prey, especially when you're hunting smaller animals. The .22LR is perfect for hunting squirrels, rabbits, and other small game. The bullet kills the animal without damaging the meat much. Plus, the rifle shooting .22LR ammo is quiet, so you won't scare off other animals in the area.

In terms of the cost, .22 vs. 9mm is pretty much a draw.
  The winner of .22 caliber vs. 9mm in competition shooting depends on the type of competition. Bulls-eye tournaments tend to prefer the .22 caliber ammo because of the low noise levels. But the 9mm is more suitable for tactical competitions. 3 gun competitions that involve speed, quick draw, and defensive shooting, require a centerfire handgun. And most of these fire 9mm.
  So this was our comparison of the two popular ammo sizes, .22 and 9mm. They're both cheap and reliable ammo, but they each have advantages in different situations. 9mm ammo is for battle use, and it's more effective for self-defense.
