A gas generant for an inflatable restraint device (for example, an airbag system for a vehicle) is a monolithic compressed solid that has a linear burn rate of greater than or equal to about 1.6 inches per second at a pressure of about 3,000 pounds per square inch. The gas generant can be in the form of an annular disk having a plurality of apertures. The gas generant may be substantially free of binder and may have a low initial surface area which progressively increases during burning. The gas generant provides a gas generation profile that improves restraint of vehicle occupants, including those occupants that are out-of-position. Additionally, the shaped gas generant decreases occupant exposure to toxic effluent combustion products and solid respirable particulates.
