I have owned, and still own Taurus revolvers. I have a model 66 that is extremely accurate, so I use it for bull's eye competition. Taurus autos are another story: I just got rid of a Millenium .380. I only managed to get through 18 rounds before it jammed up and had to go back for repair. Same experience (more or less) with others. I'll never own another one.
If you feel the need to go auto; go Sig or Glock. Less money for quality? CZ. Money not an issue? Kimber.
For personal defense, I'm a wheel gun man myself: if it goes 'click' or refuses to go 'bang' for whatever reason, no need to jack and rack; just squeeze the trigger again.
