I like the positive retention of that kydex but I cant vouch for that holster.
I have a open Carry fobus paddle that I like, but I dont use it because its open carry
I hear good things about the crossbreed holster and the holster you are showing me seems to be along that design
The Safariland 5188 paddle holster I bought is for a SIG, but is a good fit for the gun, and my hip, so I’m calling it good.
The ankle holster, think I’m going to pass. It’s rare to see anything specifically designed for this CZ .45 though.
