The 1911 or Ruger would work. The da/sa transition on the p89 will be a bit frustrating, while the 1911 will require you to swipe off the safety first and have limited capacity but get you into the 'major' category.
You'll need a couple extra mags, possibly three with the 1911...along with the appropriate mag holders. Fobus makes decent ones for a reasonable price.
IIRC 380 isn't allowed, so the Bersa is out.
