I own both a G27 and a G30. The G27 feels fine IWB, but it's about the max thickness for that mode of carry. I am concerned that the thicker G30 won't carry as well IWB. Those of you that carry a G30 concealed, what method of carry works best for you? I almost never have to tuck in my shirt. My typical clothing is pretty loose fitting. An altogether different carry question, is about when I am carrying my G30 converted to 10mm in the so called, "woods", while I am carrying a backpack. In Alaska people are more tolerant when they see me on the trail with a chest holster. In the Lower 48, not always so understanding, especially now that my permit allows me to carry concealed in some National Parks.
