It's a vintage airsoft episode as DT 10mm Auto features the MGC Colt Government Series 70 airsoft pistol that is probably older than most airsoft players... "Based on MGC's model gun Colt Government Series 70, this is used by a Japanese drama series in which Hiroshi Tachi was played as a detective aristocrat. Since the initial speed cannot be measured with the model gun, I tried to record the operation of loading the cartridge and ejecting the pod instead.
