I am not a big guy, about 6' and 170 lbs. I carry an XD40sc in a Crossbreed Supertuck. I can tuck in a button up shirt, t-shirt or whatever over my gun since the holster is tuckable. I was at a friends this morning and had my t-shirt tucked in over my xd, and he did not know I was carrying until he asked about my holster that I "normally" use. And he is a cop! I highly reccommend the supertuck. I would bet that if you went with a smaller weapon, say the p3at, tcp or lcp witht he mini-tuck, it would be virtually unnoticable
