Here is the holster that first gave me the idea
For me, my order of preference in carry method is:
1) pancake leather belt slide holster with thick gun belt. This is the most comfortable way to carry a gun on my waist. Standard fit trousers are fine, but a good concealing jacket or shirt is required.
2) IWB soft holster. This requires slightly over sized trousers, but I can use a standard belt. The covering garment need only go past the waist.
3) IWB soft holster worn outside the trousers, between the belt and the trousers. I can wear standard trousers and a standard belt.
