Thin and easily concealable yes but otherwise a pretty useless gun. Unless you can make a eye shot, good luck stopping someone with a .22. IMO, youd be much better off with a single-stack .380.
I agree with all the comments, a .22 is a plinking round for sure , but the technology of such a thin pistol is interesting...
I guess it can be hidden in thinner crevices on the body.
No man stopper for sure...but interesting technology...
