I too carry a G30 and i have tried a number of carry methods. I was coming to the same conclusion as you that my g30 may not be the perfect carry weapon for myself. I have decided to slim down to a small j-frame. I dont have the money quit yet to do that and there is no way i am selling my g30 to make that happen. I love the gun too much. Desperate for a more comfortable and a more wardrobe friendly carry solution till i can afford a j-frame i bought a smart carry holster. I have only had it for a few days and have been pleasantly saprised by how well it conceals my thick g30. I will have to say it is "more" comfy than my IWB holster. I think i may have found a solution that will let me carry my glock with more confidence and let me wear the cloths i want to wear when i want to wear them. If you have not tried the smart carry look it up on youtube. Im sure its not for everyone but its definitely worth a look.
