The Legislature has defined assault weapons as the types, series, and models listed in this paragraph because it was the most effective way to identify and restrict a specific class of semiautomatic weapons.

(C) The Legislature finds a significant public purpose in exempting from the definition of “assault weapon” pistols that are designed expressly for use in Olympic target shooting events. Therefore, those pistols that are sanctioned by the International Olympic Committee and by USA Shooting, the national governing body for international shooting competition in the United States, and that were used for Olympic target shooting purposes as of January 1, 2001, and that would otherwise fall within the definition of “assault weapon” pursuant to this section are exempt, as provided in subparagraph (D).
