This video is on the Protech Outdoors Shoulder Carry Holster.
This holster rig is a horizontal carry should holster.
This is an option that you should consider for carrying concealed weapons.
It is advertised as being able to accommodate the Bersa 380, the Keltec P-11, the Keltec P-40, The Sig Sauer P230, the Walther PPKS, and more. I use this holster for the Ruger LC9. Surprisingly, this holster works very well
