I've been carrying IWB for about 3 years. Within the last 5-6 months I've started having trouble with my lower back and carry side hip. I'm not saying it's because I carry, but it has been difficult to do so due to the problem. Because of this I'm looking for an alternative way to carry and an instructor I know strongly recommends appendix carry. Does anyone here carry that way? And if so, can you recommend a good appendix carry holster?
