摘要： A slide for a weapon conversion kit of the type used in conjunction with a firearm having a stock ejector and configured to fire ammunition is provided. The slide includes a slide body and a slaved ejector member rotatably coupled to the slide body. The slaved ejector member has a first portion and a second portion, the second portion including a contact region. The slaved ejector member is configured to contact the stock ejector when the slide body slides rearward in response to firing of the firearm and thereby causes the contact region of the second portion of the slaved ejector member to eject a cartridge case of the ammunition.

摘要： A container (e.g., an ammunition casing, a rocket housing, or the like) includes a body structure having a wall defining a cavity configured to accept an energetic material, the body structure having a central region situated longitudinally between a first side region and a second side region, wherein the wall within the central region has a thickness that is less than the thickness of the wall within first region and either less than or equal to the thickness within the second side region. A strength reduction pattern is formed at least partially within the central region of the wall such that the strength reduction pattern provides a preferred rupture path when the energetic material is subjected to a predetermined external stimulus.
