Another vote for the 9R. It’s very secure and has a well covered trigger. For me it just disappears under just about anything. I would hate to estimate the amount of time I carried my 60 in that holster.
Even though this thread is 5 years old I'll have to chime in and say Kangaroo Holster's "Air Marshal 3" is the most comfortable shoulder holster I've ever worn; and I'm not a fan of shoulder holsters.
They are extremely light, and breath. Their customer service is top shelf too.
