This is the Umarex TR50. It can shoot .50 cal saboted steel balls at about 300 fps. They will hurt and dissuade most attackers. In this Nutnfancy review I'll introduce you to its ups and downs, how the curse of the desert affected it, and its potential. It is cost effective, expensive steel ammo not withstanding. Kydex holsters are available and I'll show you some other carry options as well. Make sure your balls are seated!
