My favorite single-column-mag autoloader for carry is my Les Baer Thunder Ranch Special. In the days when I owned many 1911 pistols, I learned the full-sized 1911 was most likely to be drama-free. Les Baer pistols have frames that sit just a bit lower in the hand, because of the way the junction of the trigger guard and front strap is sculpted. I started handgunning with a 1911 in 1982 or 1983, and while there have been times I did not own a 1911, there is something very comforting about them.
I can usually dress around a full-sized pistol. When it becomes impractical to do so, well, that is why I own several snubby revolvers.
