I have a heap of holsters that are not "most carried".
I have kydex holsters, and still use them on occasion, but they tend to "peek" out of concealment for me more often.
I have several Alien Gears - I used to love them and the company. But as they went from v1-current, their comfort has decreased, and so has their customer service. Their "no questions asked" warranty now requires pictures or old parts to be sent back to them - on the customer's dime.
These days I usually carry in a OWB leather holster.
I banged out a quick holster for my 365 when I got it, intent on getting something better later, but I am just about on the point of deciding my ugly amateur work that is built to what works for me is destined to beat out the storebought models.
My latest is a Desantis thumb break holster (which I wanted as a feature.) As soon as I got it, I found it rode too high, making it MUCH less stable and it does not pull into my beltline as much, meaning it does not conceal as well.
For IWB, the only holster I have used long term is a Comp-Tac Minotaur. The shells change, but it is the same backing as I used many years ago.
Seen here next to the holster the 365 holster was sketched out from, another homemade one that I have used for awhile - this one with a bit more build quality with my P320 (M17, technically) in it.
