Does anyone here use the Smartcarry system? I am looking for a way to carry my Kahr PM9 or Ruger LCP underneath a pair of sweatpants or "warm-up pants" as well as jeans. I have looked at Smartcarry's website and they list a standard and a security model. The extra pockets in the security model is intriguing but I wonder if it adds "just enough" extra thickness to make this system questionable. Any help would be appreciated. Thanks.
