I carry my sr9c in a don hume h721 ot 36-1 (made for a glock 36). It is a non-retention, but it fits in pretty snug. With its forward cant, it lays under my forearm and is pretty secure. It you are not aware of your surrounding, even a retention holder can be defeated quite easily. I also don't open carry in crowds anyway, so I don't worry about someone getting that close without me knowing. Of course, if you are uncomfortable with something, then it is not for you. Peace of mind is very important.
