I was reading about "a trick called a 'stripper magazine'" on
Eric Raymond's IPSCC page, and decided to search the web for same.
Probably not a good idea, in hindsight (although not that serious, since SafeSearch was on and results are only brief snippets of text). Searching for "stripper magazine -sex" gave better results. (A stripper magazine, as it relates to guns, is a magazine that you use to chamber a round, then remove and load to capacity, so that you have an extra round before you need to reload.)
