The subject invention provides a grenade which comprises a means of indicating, to a user, that the grenade's striker assembly has been activated, and thus provides an indication that the grenade has been initiated. Specifically, the subject invention provides such indication of striker activation, and thus grenade initiation, which is evident to the user by touch and feel, without the need for purposeful inspection of the grenade by said user. More specifically, the subject invention modifies the grenade's striker assembly to create a means to obstruct the safety lever from returning to its original position.

Stun grenades may include a fuze configured to ignite a delay material secured to a housing including a delay chamber in which the delay material is located. A handle of the fuze may be located over a final payload chamber of the series of payload chambers, payload material in the final payload chamber being configured to ignite after ignition of payload material in each other payload chamber of a series of payload chambers. Methods of assembling stun grenades may involve positioning an obstruction in a port extending between a delay chamber and a payload chamber of a series of payload chambers surrounding the delay chamber in a housing. A delay material may be packed in the delay chamber. The obstruction may be removed, and a payload material may be positioned in the payload chamber and the port.

A stun grenade includes a cartridge having an explosive charge in communication with a fuse and a housing including a closed end, an open end, a longitudinal axis and including an internal cavity which accommodates the cartridge. An end cap is attachable to the open end of the housing, the end cap including an end wall and a side wall. A plurality of spaced first vents are defined in the end wall of the end cap. A plurality of spaced second vents is defined in an end wall of the housing. The output from an explosive charge is optimized by vents having a straight flow path. The vents have a first end in fluid communication with the cavity and a second end in fluid communication with an exterior periphery of the housing.

A grenade firing mechanism (12) includes a body (24) containing a firing pin (20) and a tiring pin actuator mechanism (22). A safety system includes twist to arm collar (70) and a safety interlock (92). The collar is movable between an unarmed position and an armed position and tire safety interlock is movable between a collar locking position, a collar release position and a firing position. When the collar (70) is in the unarmed position and the safety interlock (92) is in the collar locking position, actuation of the firing pin (20) is inhibited and the safety interlock (92) inhibits movement of the collar to the armed position. When, the safety interlock (92) is in the collar release position, the collar (70) is able to be moved between said unarmed and armed positions and actuation of the firing pin is inhibited. When the collar (70) is in the armed position and the -safety interlock (92) is in the firing position, actuation of the firing pin is enabled.

A projectile includes a body containing pyrotechnic material. A rear cap closes a rear end of the body. A pyrotechnic unit includes an ignitor in communication with the pyrotechnic material. A striker is arranged to strike a primer of the pyrotechnic unit. A safety lever is arranged initially to restrain movement of the striker towards the pyrotechnic unit. An external safety keeper is arranged initially to clamp a portion of the safety lever to the body.
