A revolver is a repeating firearm that has a cylinder containing multiple chambers and at least one barrel for firing. The first true revolver — a flintlock — was made by Elisha Collier in 1818. The percussion cap revolver was invented by Samuel Colt in 1836. This weapon became known as the Colt Paterson. The first cartridge revolvers were produced around 1856 by Smith and Wesson. The original name was "revolving gun"; the short-form "revolver" is universally used.

Revolver (stylized as RevolveЯ), is the fourth studio album by American R&B recording artist T-Pain, released through Konvict Muzik, RCA Records and his own label Nappy Boy Entertainment on December 2, 2011. It is his first album released after the demolition of Jive Records. Recording sessions for the album have taken place from 2009 to 2011. T-Pain stated that the two R's in the word, RevolveЯ have been capitalized so that in the middle, it says "evolve", indicating that T-Pain has evolved as an artist, and as a person in the period from Thr33 Ringz up till RevolveЯ. He later stated that the R's were put to show how people can be deceived, and precept incorrectly without looking at the inside of things, and he then said that this will be the scheme of the album. T-Pain announced that the album will be released on December 6 in the United States in an interview with Lady Jade on the F.A.M.E. tour bus, concidentally this is the same release date of his first album, Rappa Ternt Sanga back in 2005. At the end of 2009, and throughout the early part of 2010, several singles were released from the album; however, the poor chart performance of these songs caused them to re-dubbed as promotional singles.
