............."Assault pistols", at least according to according to Los Angeles County Sheriff Robert Luna, who wrote:

"The weapon that we recovered at that second scene I am describing as a magazine-fed semiautomatic assault pistol. Not an assault rifle, but an assault pistol that had an extended large capacity magazine attached to it."
