I never owned a 1911, but if I did I think I would prefer a fully ambidextrous probably because I am ambidextrous. I 'm actually left eye dominant and Im lefty with rifles and bows. Im a very good shot using handguns left handed but for some reason that I dont understand why, I prefer a right handed handgun. One thing for sure is that I'm an excellent point shooter right handed. I like revolvers very much and they are right handed and I never had a problem doing reloads and tossing it to my left hand for use. Glocks are my favorite and I dont have a problem using right handed controls and tossing it to my left hand for use and tossing to my right for reloads. Definitely I got a whole lot of practice switching hands in more ways than one. A secure transfer needs practice.
Personally, I prefer plain guns, smooth with minimal controls and features to prevent snagging, this is probably the reason Glocks are my favorite. This preference, however is mainly with concealment for serious use in mind. I think that for OWB uses I would prefer to have 2 guns, I dentical ambidextrous 1911, or 1911 style handguns(maybe HKs) that wouldnt matter to me which holster they end up being in. Glock wouldnt be good for this because thay can only have a mag release on one side at a time.
