What are you referring to?
Handguns, they have power at close range. Especially when using hollow points. You need them if you ever are in a dangerous situation. They are 1 hit.
If you hit in the right spot almost anything is one hit.
However, to stop someone coming at you, generally you will need multiple hits with a handgun.
I never said they weren't powerful. Shotguns and rifles are much more powerful.
The .223 bullet from a rifle travels at about 3000 fps.
A 9 mm from a handgun travels arond 1100 fps
A .45 is about 900 fps but is much bigger than a 9 mm.
In any case the massive amount of energy from the .223 makes one hell of a mess when it enters the body.
A shotgun buckshot or slug is much more powerful because it's a much heavier load.
A 12 gauge 00 has 9 pellets about .33 caliber each. That is extremely powerful.
There is a joke that I will paraphrase.
A woman sees a Texas ranger.
Woman- I see you are carrying a sidearm. Are you expecting trouble today?
Ranger- No ma'am if I expected trouble I would have brought my rifle.
