Approximately the size of a Walther PPK/S concealed-carry pistol, the Bobson uses 6 millimeter bullets, fed from a 23-round capacity magazine conventionally loaded into the hand grip. Bobson 6mm rounds are HV-class (high-velocity) in nature, and are suggested to behave similarly to 10mm rifle ordinance. In appearance, they are much slimmer than traditional 9mm handgun bullets, and also significantly longer.
