Is it really possible to carry something like a G30 or Colt Commander IWB and it not print? In the summer with a T-shirt it looks to me it would be next to impossible for it not to print. Winter you could carry about anything due to jackets and coats. I'm 5'-9" and 160 pounds and don't think I cold completely hide either of those, my chosen two even with a Crossbreed Supertuck. I've never tried, just imagining. Even if you put your billfold under your shirt it's going to show.
