I would imagine that you are not dealing with any different issues carrying than any of us.
Go through the list of diagnostic questions and see if that can't narrow it down a bit.
Inside waistband - IWB
Outside waistband - OWB
Where are you going to carry? Mostly home or work?
Can you carry at work? or will this be for nights and weekends when you may be able to dress down a bit?
What is your clothes style? business or casual
Do you feel you want to carry on your side, cross draw, or ankle?
Go through the many holster threads we have going at any given time. Look at the pictures. Go to our Sponsor sites at the top of this page: AIG Tactical and Little Bear Holsters and spend some time looking at their stuff. You may not know what you want but going through photos can rule out what you know you don't want.
Don't buy something for looks, buy it for function.
Does this help?
