A few years ago I carried 5 guns all day just to see what if it was doable. I had 2 .45 pistols IWB, 1 on the hip and 1 in the small of the back. A .45 revolver in a shoulder holster under my shirt. A .380 pistol in an ankle holster and a .25 pistol in my pants pocked. Made it all day with just a little discomfort in my back when I was seated. It wasn’t too bad but I only did it once and don’t plan on doing it ever again. I just carry one on my hip now and am good with that.
