The Model 442 Airweight Centennial is the aluminum-frame fully-enclosed-hammer J-frame in .38 Special, closely related to the stainless 642 but with an aluminum cylinder as well as frame, reducing weight to approximately 15 ounces. The Centennial design with fully internal hammer provides the cleanest possible draw from a pocket holster or waistband. A classic concealed carry choice for decades.
