I was out all day today with a .357 snubbie, t-shirt (loose fit), cargo shorts and a JIT slide holster. Kind of like a cheap Yaqui slide type. Never worried about printing and the shirt is long enough to cover everything.
The holster sits right behind or in from of my hip. When I've got my 1911, I use a similar holster type that rides high. Sometimes I wear a short sleeve shop shirt. Just have to practice lifting the shirt and grabbing the grip to draw.
