I know it's NOT for everyone, but I've carried inside the pants with a SmartCarry for over 10 years.
Cool weather's not here yet, so I can't use a full shoulder rig.
But I would
like to utilize the "shoulder holster" concept.
This week I've been using my old, worn SmartCarry system as a quasi-shoulder system but just strapping it across my chest with the Kahr CM9 under my arm.
No, it's not perfect. No, it's not the full, "ActiveProGear" rig (which I just bought and returned). No, it doesn't feel tight and restrictive.
Yes, it's comfortable and it works
Unless one has to button their top button or wear a tie, it might be an alternative carry system.
And, Woolrich, makes long-sleeve shirts with two fake buttons on the front with magnets in them. That shirt really
works. I bought two of them.
