I'm looking for a holster to conceal my M&P and was wondering if any members can give some insight on the Raven Concealment holster? Do you carry it OWB with a shirt over it, or IWB? Is it bulkier than a CBST? I've found the CBST to conceal my firearm very nicely, but have wanted to try out a kydex holster for some time. I'll be using it for every day concealed carry.
