My favorite holster that I use exclusively for concealed carry is a Kholster. It is not pretty, but it is not suppose to be seen. Also it works well with my shirt tucked in or out.
I carry a Glock 30 45acp although my Glock 21 fits the holster and works just as well.
The Kholster is very comfortable and I forget I am wearing it. It also is made for many popular models of guns.

I looked at the site.
Is that circle leather? Almost looks like wood! :)
So if you wear this on the side, don’t you need pansts with a bigger waist?
