After hours of checking out shoulder Holsters I decided on the ShapeShift Shoulder Holster for my Sr9c - https://aliengearholsters.com/ruger-sr9 ... lster.html
I have a couple other ones outside and inside waist. Just not as comfortable as a shoulder holster plus you can reach it while sitting down and driving easily. And I feel these guys make the best design. You can adjust it in several places and change up the cant. They offer a 30 Day Test Drive that offers a month-long trial period with a lifetime warranty.
I have a shoulder holster for my Blackhawk too but not nearly as nice as this.
