Colt had a number of guns that ran for only a year or two. The Viper is just one of them.
The only appeal of the Viper in today¬ís marketplace is the fact that it carries a snake name. It has become desirable because many guys seek to have a so called ¬ìSnake Collection¬î and the named Viper must be included in such a collection.
The Viper is nothing more than a Police Positive Special of the same vintage, except using a lightweight alloy frame.
