I use a Bianchi #100 for IWB carry for my 1911 and for my Kahr P9. I first used a nylon IWB holster for the 1911 and the beaver tail killed me. The Bianchi has leather between the beaver tail and your skin. Protects very well. Size 14 fits the 1911; size 9 fits the P9.
Keep the beaver tail. I carry cocked & locked.
