I have a IWB holster that works really well unless I wear a crappy belt. The one and only time I did my jeans slid down and somehow the clip slid off of the belt. Just as I felt the gun, holster, and all was about to fall from my waist, I quickly clenched my elbow against my side and went off to find a room to adjust myself leaning and clenching all of the way. Luckily my shirt was untucked which helped retain it and at least conceal it. Just another one of my little life lessons I keep learning. No more cheap belts. Ever!
