They are refered to as IWB holsteres. Inside waist band holsters. I enjoy a IWB holster but it has to be adjustable for the angle at which it sits. I am a larger framed person and it is uncomfortable for me to have certain ones. That is why I had all of mine made. Comfort to me is extremely important for something I have to carry for several hours at a time. Walking, jogging, etc.. is not a problem but sitting down to eat or drive a car is different. I have a seperate firearm in my car usually, but my ultra compact 1911 has to be comfortable when I sit down, etc. Plus you have to be able to tactically draw and defend yourself. Goodnight.
