People with Glock 19 (or similar sized handguns), how do you comfortably carry IWB (new to CCW)?

Just started carrying a few days ago... so any help is appreciated. I have a Hanks Gun belt, Alien Gear Tuck 3.0 (IWB) holster, and a Glock 19. I'm 5'9" and weight about 160.I've been trying carrying in a few different positions. I tried the 3:00, but couldn't do so without printing like crazy. I tried the 4:30, but couldn't sit down comfortably, and so far, the 5:00 position seems the most comfortable (without printing), but its still pretty damn uncomfortable. What am I doing wrong?Thanks for the help. via /r/CCW http://ift.tt/2bznuFX
