High Quality Content by WIKIPEDIA articles! The phrase Saturday night special is pejorative slang used in the United States and Canada for any inexpensive handgun. Saturday night specials have been defined as compact, inexpensive handguns with perceived low quality; however, there is no official definition of "Saturday night special" under federal law, though some states define "Saturday Night Special" or "Junk Guns" by means of composition or materials strength. Low cost and high availability make them attractive to low-income buyers despite their shortcomings.
