I carried a Colt New Agent and a Kimber Ultra. Both were great carry pistols. I've since gone to the Kahr PM45, which is similar in size. I also carried my Kimber Pro occasionally. Some things I learned:
1) The grip length is very similar between the 3" and 4". If you are willing to add just a hair to the size and weight, the 4" Commander/Champion/Pro is a quality pistol to carry.
2) If I had the money I would absolutely go with a bob-tailed commander. That pointy grip tip is tough to carry for me.
