Between the two, I like Sig. Sig has the name and reputation.
Taurus' can be a crapshoot sometimes on getting a good one. That being said, generally the PT92 does well as far as reliablity.
Side note, you may want to post this thread in a more pertinent subject heading. The admins might move this thread to Taurus or Sig forum. This particular one is for 1911s. Just fyi.
Good luck with your choosing! I owned a Sig 2022. Didn't fit my hand well, but was a good gun.
