The most common factor for people having issues with carrying is that they usually do not have a good belt. The belt is the most central and vital to any carry array. I’m surprised by the lack of information and discussion about this central piece. There is a very distinct type of belt for carrying.
Look for belts that have durable material and are thick and wide. Avoid belts that feel flimsy or can be bent across their width. Problems with printing, holster ride, and chaffing (to name a few) stem from an improper belt that cannot support the weight of a firearm.
