The Fobus SWC from the C Series is an Inside the Waistband (IWB) holster offering passive retention. This design involves the J clip being worn over the waistband, but positioned behind your belt. This ensures that the belt's bottom is resting in the clip, a design feature that limits any movement of the holster when you draw your firearm. Additionally, the passive retention automatically engages as soon as you re-holster your weapon.
