I just bought one for my XD40, I'm wearing it right now. I want to get use to it and I also want to get use to carrying my XD, ready to go. I am going to the DMV tomorrow to pay my CC fee, wait 24 hours for my app to get in the system, get fingerprinted, then wait.
So far, worn it for two nights. Comfortable, nothing digging into me, my XD fits snug and doesn't make any noise, I could see where things hitting it could. Secure, I have pulled on it, yanked it, tried to lean against the door frame to see if I can get it to release and I can if I hold it, put it right on the release and wiggle around, my wife thinks I have lost my mind by the way.
I got work on the cant so that it hides better, I am showing a print pretty good. Luckily, in Tennessee, the state doesn't specify if we have to conceal or can carry open, so the law has been interpreted as both. I still don't want to announce it.
