I've been wearing my 642 in a Renegade (with the elastic pull-through retention strap) every day on duty for over 13 years. I'm on roughly my 4th holster as the elastic gives up after several years of being stretched over a boot. I also wear it off-duty most of the time. These holsters are secure, comfortable, affordable, and quick to deploy. I unconditionally recommend them for revolver carry.
As a side note, I have mine slightly customized by the manufacturer. I have a little extra hook/loop added so it will securely fasten around both a bare ankle and a duty boot.
