As part of this ongoing evaluation process, we have received reports, in an extremely small number of cases, that the firing pin safety plunger of the SW1911 pistol can become disabled, creating a situation where the slide may jam and render the firearm inoperable. This only pertains to certain Smith & Wesson Model SW1911 pistols bearing serial numbers JRD0000 to JRD4750
