That looks suspiciously like "crotch" carry to me.Welcome to DCDC. My standard spiel for AC is here (not my video I just like the way he breaks it down). Watch this and have fun!
As badly as i wanted one, Im having something very similar being made custom locally with only a 7-10 day lead time...i may end up with a sidecar down the road though!I carry my XDS in a T.Rex Arms Raptor Holster, love it. As far as the belt is co corned I keep it pretty snug but not uncomfortably so. I find the 12:30/1:00 position is the most comfortable for me and allows me to sit/move without any issues.
Regarding the printing issue for the g19 grip, an important feature for an aiwb holster is to tuck the grip into the body to minimize it. Check out my review of my Raptor Holster https://youtu.be/C-M66gQ1ndg
+1 Different gun/style/holster/belt/needs. Adjust to your comfort and need. Sometimes NOT comfortable. Deal with it.I found I adjust my belt for different pants. Sometimes it seems like the holster is moving too much. I also move the holster between 1:00 and 2:30 depending on Holster and gun. In general I keep the belt tight enough to have minimal movement.
