When I bought my first firearm, I had no intention of ever carrying. The sales guy said, "you'll have another gun within 2 months, your CHL in a year, and a drawer full of holsters." I laughed. He was right, of course.
Some of my big learnings as I've gone through this holster journey:
1. As with firearms, gun guys want you to buy the holster/gun that fits THEIR needs or quirks. You need a Glock/Sig/Crossbreed/Don Hume! -- even if you don't.
2. You can carry a MUCH larger firearm than people realize, by either dressing around it, or finding the right carry location and/or holster.
3. Sometimes, cheap really works!
4. OWB blows IWB away for speed of presentation. .5 seconds is an eternity in defensive situations.
5. "50 million Elvis fans can't be wrong". When everybody who tries a holster or type of holster raves about it, it probably lives up to the hype.
The journey is a fun one. The drawer keeps filling-- even when we love what we already have.
