Suggest you take a look at the holsters made by Simply Rugged. There OWB holsters are very suitable for the reason you want one. They are simple, but well made, not expensive especially for the service they will give you, and allow both strong side and crossdraw carry. Simply Rugged is an excellent vendor in my experience. They are not bulky and will carry your gun with about the smallest presence on your waist belt. They are very secure without any straps, but you can over them with a safety strap if you need one. Your holster will be built exactly to fit your gun. If necessary, you can contact them by email with questions and they will be quickly answered.
