FWIW I carry my LC9 in a Galco pocket holster a lot in the summer when I'm wearing loose shorts & T-shirts.

I carry the LC9 in a Targus brand hybrid holster (leather base with a kydex shell) IWB @ 4:00 most of the rest of the time. For any holster a good belt is essential, just as others have said.

I own a few shoulder rigs, but I am so barrel chested that they don't work very well for me. Th gun causes my arm on that side to "hang" farther away from my body on that side - kind of gives me a one-sided "gorilla" stance.

I've ankle carried with a holster inside my cowboy boot, but most ankle holsters are uncomfortable IMO.
