Slow Learner,
The "stick in the barrel holster" he is referring to is the Versacarry. It's very simple: slip the rod into the barrel, clip it to your belt, instant IWB. I don't like the concept either, but that company is making a ton of money selling them. There are actually 2 companies retailing similar holsters, but I can't think of the others name.
I hope you notice I made my suggestion without the bias of the other contributor.
