If going concealed carry look at the Kimber line. Great line of weapons. Full size you can't beat the Colt 1911/1991. Springfield also makes a good gun. This model has been copied by virtually every maufacturer out there in some form and for a good reason. For stopping power go with the .45 it can't be beat but if control is an issue something with a little less recoil, look at the 9mm or .380. Personally have a full sized Colt and concealed carry Springfield both are great guns.
