I have one, and I would consider it up to Javelinas and dogs. It is light, handles well, has a twelve round magazine, and its accurate. You could do worse. I especially like the low level of recoil from it. With the extra magazine along for the ride, you would have an excellent self defense field pistol.
As to concealment, I cannot quite make a (pants) pocket pistol of it, but with an inside the pants holster or even a small belt holster it should be little noticed. Mine carries well in a vest pocket too. Just remember to keep it in some kind of holster to protect the trigger from accidental movement. I use a pocket holster and feel confident with that.
We have Javelinas too. You get enough of them in one place and they will start looking at you as lunch.
