During the long and sweaty summers in Louisiana, I carry my hammerless 2.25" SP101 in a Mika pocket holster, either in the front or the back. With an untucked shirt, it's invisible even with short pockets. With deep pockets, it's also invisible even when shirtless or with the shirt tucked in. The slight bulge in my pocket is my cellphone, if anyone were to ask (noone ever has).
In the winter (about a week here in Louisiana), I often use a j-hook under the belt in the waist, on either side.
