I have diagrams and understand the inner workings of the M9A1 rifle grenade, does anyone have a schematic or drawing of the internals of a M9 Rifle grenade? I would like to see how the grenade type safety pin works or what is releases when it is pulled out. There must be some sort of detonator inside the base similar to the M9A1 that is activated when the fuze strikes the object and I would like to see it. There are some pictures of disassembled grenades on the web but none of them appear to be complete. Thanks, regards,
