I have one of these in my safe. I am thinking about starting to carry it daily. Seems to me things are getting worse in the world and why not carry all the firepower you have available? I know some are going to mention over penetration but that is a undocumented myth created by the FBI when they wanted to get rid of the 10mm because of some agents not being able to handle the recoil. I saw a guy on TV hit a target at 250 yards with a 10mm Glock. I don't think any of the other calibers will come close to that.
