I had the wonderful opportunity to meet the guys from Raven Concealment at the LAV Low Light II class and was very please with their work and presentation. I have since purchased a Phantom holster for my M&P 45 and find myself being very pleased. I would like to explore the IWB options that the holster is capable of being configured into. Any input as to which of the two IWB add-ons (Over hooks or the J-Hooks) would be appreciated.
