I have a Done Hume leather IWB, for my Walther/S&W PPK/s, works very well with jeans, and OK with shorts due to the weight of the PPK, a good belt is a must regardless. Seems to work better slightly further back than a standard strong side application.
It does require an untucked shirt. It is made very well, and works. Holsters are like socks, some like em this way, some like em that way.....
My Kel-Tec rides in a Desantis Nemesis, works like a champ in front or back pocket and in shorts.
Test drive em if you can, I also like the Galco Summer Comfort line for larger pistols, ie my M85 Snub....
For quick trips to the grocery store, routine errands, etc,... the Desantis is the quick and easy.
