My EDC is an XDm 9mm Compact. My current holster is a fanny pack. Been wearing it with a full 19 round spare mag for 3-4 months now and getting a lot of low back pain. I've left the spare mag out a few days and it seems quite a bit better. Even so, I'm thinking about switching to IWB. A lot of my carry time is commuting to/from work, but I can't carry at work. Pretty sure they don't want me wearing an empty holster either. So, I need a holster that's pretty easy to take off when I get to work. I can lock the gun up in the car and in a NanoVault. Also, I want a holster that's not going to jab me to death while driving. My normal clothing is business casual, which means no jeans and tucked in shirts. I do not normally wear a sport coat or jacket other than for cold weather. (Summers here in Tulsa don't require much of any jackets! ) I am willing to make some changes in clothing if necessary. OK, so I'm dreaming the impossible dream. Any dream makers out there? I'm looking for any (useful) advice on the subject.
