I usually wear the ones with flex material, either jeans or business casual. I find these are more comfortable when not carrying and work good when carrying. I also use a good belt and sometimes a pair of undergarment suspenders, they help with the extra weight on the belt.
I can see a serious delay in Pistol permit transactions now that the same agencies will be processing rifle transactions. Probably be waiting a lot longer. I am sure this is part of the plan as well.
