Abstract: A holster for handguns, of composite construction including a handgun-holding pocket of laminated flexible material including a layer of a resiliently compressible foam material, with a frame of rigid material attached to the pocket structure, leaving the pocket structure free to move slightly with respect to the frame. A compression band surrounds a portion of the handgun-holding pocket to compress the layer of resiliently compressible material against the surfaces of a handgun held within the holster to provide resistance against withdrawal of the handgun. Anti-twist plates may be provided to resist unauthorized removal of a handgun from the holster, and a security strap and thumb-break are attached to the frame of the holster but not attached directly to the handgun-holding pocket.
