Welcome to Bersa Pistol Forum Melaflander34 from Hurst, Texas.Greetings!
I ran into the same issue trying to find a holster for my UC45 and actually went with a leather one made by Tagua.
Amazon.com: TAGUA Quick Draw Belt Holster HK45 Auto,XD, 24/7, Millenium, HiPoint & FNP45: Sports & Outdoors
I paid $37 at the local gun store. I love how it wears and it sure it snug. I have run across streets with it, no issues. Jumped off a break water onto sand, no issues. Easy to draw. The only issue you might have (which I did at first) was the fact that it doesn't have any "safety".
