The only one I was ever able to find for mine was a Fobus made for a Beretta 92. It was either that, or any number of generic one-size-fits-most holsters.
If you ever hit the Indy 1500 gun show, Raven Concealment could custom make you one of their kydex holsters.
There are a lot of belt slide holsters in leather or nylon with or without thumb break. You need to try it and sometimes you can use it with other autos of that design.
