In the winter I tend to carry larger pistols. I've carried: XD45 service, Colt Commander, HK USP 45, CZ 75b, even a Ruger Alaskan just for kicks under a hoodie or untucked dress shirt in a open top slide holster. In the summer, I carry a Taurus PT145 or a Kimber Ultra in a Uncle mikes IWB cheapie at high noon (mexican carry) under a T-shirt, or any of their bigger safe-mates in a slide under a short sleeved dress shirt. I am going to buy a Kahr MK40 soon that will probably be my primary summer CC when I'm alone. I tend to carry bigger, higher cap guns when I'm with my family. I just feel better with more firepower when I have them to defend also, and I dress around the gun.
If you're wider in the shoulder and narrower in the waist than normal, it's easier to hide the bigger iron.
A good belt is a must.
