Just got back from a 5 day trip to Gatlinburg, Tn., & surrounding areas. Wore the IWB holster for my Sig P250 .45 that he made, for about 9 hours a day, average. The drive up there,& back, in & out of the car, driving around, some light hiking, etc. Not one bit of discomfort the whole time. This is one of the best equipment purchases I have made.
