The Jaguar is a double action, the Poison was a blow back. Fromm what I remember way back then, the Poison only came in a silver finish.
The Poison made a bit of history when it came out because it retailed for only $299. This was at the time when a Bushmaster SI Deluxe (Pump) retailed in the mid $400. The PMI-3 was close to $500, and the Automag was simply ridiculous.
As far as the dawn of the semi age, the Poison was equivalent to semi's as the Ion is to electro's.
