“The absolute BEST 9mm handgun available! This little pistol packs a wallop and delivers high-quality manufactured precision lethality with minimal kick. Rechambered to commonly available 9mm rounds, this is a reliable handgun that will keep punching little holes in paper or flesh targets as long as you keep pulling the trigger (and reloading). If you’re looking for one gun to carry for any occasion, from nights on the town, to mornings in the gutter, this is the GUN FOR YOU! Optional blade attachment may be available; if your package has sharp edges, it is included.”— Crazy Ivan's description
