Must be nice to still have guns. I sold all my long guns locally to concealed carry card holders (I'm responsible like that) and lost all my handguns in a tragic kayaking incident last summer.
The holster is a Pancake style made my Lobo Leather... They make great holsters, belts and so on. I will find a link and send it to you. @Seacowboys turned me on to them a while back.
