I have been carrying my XDM in a K Holsters IWB (supertuck knockoff) about 4:00. I believe it carries and conceals pretty good. It is comfortable but I have to be carefull when bending over or raising my arms. I carry everyday all day.
I believe when it warms up I will be going to the sub compact in the same holster.
Right side I have a Springfield Armory 1911 Gov in a Crossbreed IWB SuperTuck.
I am giving up the G22 this week though and going to a G23.
