I wanted a simple but rugged and inexpensive holster for hunting. One did not exist it seemed but I was told I could stretch a slim jim style meant for a NMA/1860, which I did and am well pleased. Put my ROA in a plastic bag and moistened up the leather. It’s a very snug fit, so much so I can turn it upside and shake it without it dropping. That takes a good bit of force to do. I believe it’s from Oklahoma Leather.
