I've been carrying everywhere I go for the last few months, and have been CC'ing since I got my permit a month ago. I bought an IWB holster from an eBay store that custom makes them, and my gun fell out of it today. Been using it for awhile and it's the first time anything like this has happened. I think it was positioned in such a way that maybe the momentum from my moving leg pushed it out of the holster? I can say it was 100% secure when I put it on in the morning. Best part was it happened while I was grocery shopping! Only two people seemed to notice though, and even then they went back to looking at bourbon. So, now I'm in the market for a new IWB holster, because that really shouldn't happen..
