I usually carry a Glock 27 .40S&W. It is thin enough, that I carry it in an IWB holster (Galco King Tuk). I just bought a Glock 30 .45acp. It is thicker than the Glock 27 and I have my doubts that it would work well IWB. Do any of you carry a G30 concealed and what have you found to be a comfortable way of doing it? I'm fine for field and range holster for the 30. I just need something for when I carry it concealed.
