I don't have a problem hiding a .45 1911 Commander under a t-shirt. Just stay with smooth grips, a IWB holster with a cant and a good belt.

If he has small hands I would recommend a CZ75 or Browning Hi-power in .9MM.

I starting to like the CZ75 more and more. It can be carried "cocked and locked" a la 1911, but has a safety that is easier to manipulate than a Hi-Power IMO.

Small hands can work fine with a 1911 if your fingers aren't too short. I've got what I consider to be smallish hands for a guy but my fingers are long enought to handle a full size 1911 just fine. If my thumb were a 1/4 inch longer I could reach the mag release button a lot easier though.
