I just bought one of these: http://lynchcombatsystems.com/ And I love it..! I was looking for an IWB system to replace my uncle mikes cheapy and a friend tried to turn me on to a "king tuck". I didn't care for how bulky and thick it was. I found these guys last week and bought one for my G23, and I can't recommend it enough. It works IWB and OWB and is so light weight that I actually forget that I have it on when I pull my gun and mags out while I'm around the house. I actually fell asleep with it on. One of the selling points is that you can keep this on IWB with your gun and mags when you go to the toilet. Totally true, I have done it twice..!
