yes it's good
Got one, never did carry it much, but never was real worried about myself when I did
It puts a 32 size hole in what you hit it with, pretty much anything short of steel or rock or sand or dirt.
Them bad guys with steely eyes mostly tend to get all misty eyed if/when you shoot at 'em, if they not be too busy running the other direction

Not my 1st choice in what I would recommend to close family, but none in our family are on active combat duty or LEOs.
Yet for all the scenario stuff so common on gun forums, the number of ugly situations which have been defeated by some average-joe with a 22 rimfire so far outweigh the number who lost out on account of not using a 45acp or 357, you have to google hard to find anything remotely near the examples of the 1st kind. Which a lot of folks do. Which is fine.
The "consequences-of" vs. the "probability-of", that argument cannot be ignored.
But how adventurous a lifestyle you choose to live, and where lived, that also counts for quite a lot.
Some folks really do need a backyard bomb shelter... but not everyone does.
Most of us are ok with somewhere in the middle, even the light side of middle.
all a matter of subjective perspective.
PS
yeah, a 32S&W/L revolver with wadcutters really is one of the all time great bullseye shooters
and a 32 acp beats a cell phone whip antenna so bad for self defense it ain't even funny
and the 32 S&W/L just might be the all-time best centerfire revolver trainer to learn on, whist you ponder your next step up the power factor ladder
