What's somewhat funny with this topic. Myself speaking, I can show/prove why in the world of all calibers used in handguns the .22lr. Is not a good choice and maybe even the worse for use as a self-defense caliber. But others will say it is a good choice. The funny part is those that are on either side won't be persuaded to change their opinion to the other. Since this topic seems to come up over and over.
I am done.
I don't care what anyone uses. It's their life and their choice to make.
Generally, many posting questions are just trying to get validation for their choices. Some might just be having fun to get 6 pages of back and forth. Who knows.
