I sometimes carry a 3" K-frame (S&W Model 10).....in a Bianchi 111 Cyclone holster (belt holster with thumb break). This is done strongside, with a 20 or so degree forward cant - approx. at the 2:30 position. Lately though, I've carried my Taurus 851 snubby or one of my autos more often. The snubby usually goes in my right front pocket, in a nylon pocket holster. I also have a paddle holster for the snubby, which I wear crossdraw at the 10:00 position - but not too often, because this seems to print a bit too much. I've tried the snubby in the same holster at 2:30, but for some reason, it tends to print even more. The autos always are carried in a Gould & Goodrich Yaqui belt slide, in the 2:00 to 2:30 position. Neither of my autos are "pocket guns", but oddly enough, they don't seem to print as much.
Oh and as to cover for this - I wear an un-tucked shirt, usually a T-shirt, about one size larger than I really need, in the warmer months. In the winter, the shirt will be tucked in and I'll wear a loose jacket - but the guns might move to the 3:00 - 3:30 position, depending on circumstances.
