I'm thinking about picking up a Ruger SR22 to use solely as a concealed carry gun. I like the idea of this because it's small enough to fit in my pocket, I have a few thousand .22 rounds on hand already and I will be able to shoot it a lot without breaking the bank. I also like the true safety on the SR22. Are there any cons to this gun that I'm not thinking of? The most obvious con is the lack of power of a .22, but it's obviously more than enough power for self defense purposes. Thoughts?
