I like shoulder holsters and think they are very comfortable especially for a heavy gun. However they are pretty poor choices for conceal carry unless under a suit or button/zipped up coat. I seldom wear mine unless it is cold weather and I'm going to be outside with a jacket or hunting.
Your "chiefnpd" seems to indicate a cop. If that's true, you might get better feedback from your associates in the department. They might have more experience with daily shoulder-rig use than anyone else here.
I was a police officer for 26yrs. I have moved across the country so no longer have personal contacts. I live in So Cal. and was having trouble locating a shoulder holster for the cw9 with ct. Thanks for all the comments.
