A reusable gas-powered hand grenade is provided. A hand-held housing defi one or more launch tubes. A projectile is loaded in each launch tube with an obturator being positioned therein between the projectile and the launch tube's muzzle end. A sealed reservoir is maintained in the housing for storing a gas under pressure. A rupturing device is mounted in the housing for breaking the reservoir's seal upon impact therewith. A triggering mechanism coupled to the rupturing device maintains separation between the rupturing device and the seal until the triggering mechanism is activated. Once activated, the triggering mechanism moves the rupturing device to impact the seal so that gas pressure propels the projectile and obturator from the launch tube.

[ What is claimed as new and desired to be secured by Letters Patent of the United States is:] [1.] A reusable practice hand grenade, comprising:a housing defining at least one launch tube having a breech end and a muzzle end;at least one projectile loaded in said at least one launch tube between said breech end and said muzzle end;an obturator positioned in said at least one launch tube and abutting said at least one projectile, wherein a portion of said at least one launch tube extends beyond said obturator towards said muzzle end;a reservoir maintained in said housing for storing a gas under pressure, said reservoir having a seal;a rupturing device mounted in said housing for breaking said seal upon impact therewith, said rupturing device defining a channel through which said gas can flow from said reservoir to said breech end when said seal is broken; anda triggering mechanism coupled to said rupturing device for maintaining separation between said rupturing device and said seal until said triggering mechanism is activated, and for moving said rupturing device to impact said seal after said triggering mechanism is activated wherein said gas enters said breech end of said at least one launch tube to increase pressure on said at least one projectile sufficient to propel said at least one projectile and said obturator along said portion of said at least one launch tube and from said at least one launch tube.
