Everyone has warned me of those holster purchases that for one reason or another just don't work out and you end up tossing that holster into a box of unused holsters. I've been fortunate enough to only have two holsters end up in the unused box. A Galco Stinger for the wife's BG380, great holster but just didn't work for her. And a custom kydex pancake holster by ArmedCivilian556 it had way to much retention for my preference.
My current fav EDC holster is my trusty Crossbreed Supertuck with Horsehide Leather.
What is in your box o' holsters and why didn't they work out?
