I just spent about 10 days with this setup on a road trip vacation that included "big city attractions" in Nashville, hours upon hours of driving, hiking in Alabama, and puttering around in Gulf Shores. What I learned:
It's pretty damned easy to conceal in anything I want to wear.
The speedloader setup doesn't work with a larger belt buckle and leather belt, despite working fine with the Graith belt. There's no room with a thicker leather belt and an Lansky Bro's Elivis "TCB" belt buckle. (https://www.lanskybros.com/TCB-Belt--P2083.aspx this buckle, but not that belt. If you're a hillbilly retard like me and are into this sort of thing, they sell the buckle separately and I think it was under $30) I made due with two speed strips when I wasn't wearing the Graith.
It's very comfortable while hiking, walking, eating way too much shrimp, etc. It's reasonably comfortable while seated, but can get uncomfortable if you let your pants fall down a bit as you sit. I got a little fidgety in the driver's seat during a 6-ish hour leg without stopping and managed to work it down too far and had to move it around a bit so it didn't jab me in the leg.
I think @blues was the one who mentioned threading the belt opposite of how one normally would. I tried that so that the tail is on my left side and it was more betterer.
