With pratice, follow up shots on target are not a problem with any of the calibers chambered in the Para or Kahr. If you are comitted to 24/7 carry, I'll wager you'll end up with a least two guns in the first year. One you'll carry all the time. The other you'll wish you carried all the time. I'd have to take inventory to count the handguns I currently own. I have been carrying over 30yrs, and shooting a lot longer. I frequently find myself carrying an 8oz .32 or a 16oz 9mm. Not ideal, but beats the 2lb .45 I left in the car. Carry guns are a personal choice, it's a lot of fun solving the problem of finding the right ones. I tend to make the gun match the clothes rather than dress to conceal it. No way I'm wearing a vest in 100 degree weather, or a fanny pack anytime! My idea of concealed is carrying in such a way that no one suspects I have a gun. That's hard to do with a large or heavy gun.
Good Hunting!
