I have customers that have RIA and AO 1911's, they seem to be decent for the price paid.
The RIA 1911 in 38 super can be picky on the ammo it will feed.
I would stay away from the new Reminton 1911's. The VIS in some of the frames is not up to spec ( they were machined wrong) and it will be a major cost to repair.
Never had a Taurus or Ruger on the bench so I can't give an honest opinion on them.
However if I was going to spend the money they cost I would buy a Springfield Mil-Spec.
