Sorry, this is a pet peeve here. Just a clarification. Real fights now do not involve automatic pistols. If you are in the states, the gun laws of 1968 ( I think that is the right one) essentially elimated AUTOMATIC weapons from the hands of people, (i.e not the govt.) You may indeed be refering to SEMI-automatic pistols. I know this may seem a small point, but it is sort of like calling a tanto a katana, or a twin turbopro plane, a jet.
Thanks for the rant.
In my youth (1950's - 1960') the pistols were zip guns, later "saturday night specials". When I was a probation officer in Los Angeles County in the early seventies, the "saturday night special" became dominant and began to shift to heavier artillery.
Actually, as I grew up, the name for automatics became machine pistols. Let us simply declare a truce on terminology and say "rapid fire".
And, no, the last time I looked, the tanto, wakizashi, katana and dai-katana were all different lengths.
