Biggest help is a high quality holster and belt, in the spot you've chose to carry. If you have to wear a tucked in shirt, then you need a smaller gun and either a pocket rig or a tuckable holster. Do you wear a covering garment at all, vest, light jacket? One of the things about CC, is dressing around the gun. I'm a fat old man who doesn't care what people think, so I dress like a sob, and conceal a full size CZ P-09 easily with High Noon holster and belt.
