"M&P" stands for "Military & Police" and is used to pay homage to the Smith & Wesson .38 Military & Police revolver.[2] According to the company, the .38 Military & Police, now known as the Model 10 revolver, has been in continuous production since 1899, and over six million units have been produced."[3]
The M&P15 was introduced at the 2006 SHOT Show in two varieties: the M&P15 and the M&P15T.[4] Both are basically the same rifle, chambered in 5.56×45mm NATO, with the T-model featuring folding sights and a four-sided accessories rail fore end. They include the standard direct impingement gas system. In order to decrease cost on the original design, both the dust cover and forward assist were omitted. These rifles were initially produced for Smith & Wesson by Stag Arms, but marked and marketed under the Smith & Wesson name.[4] Currently, Smith & Wesson makes the lower receiver in-house, while the barrel is supplied by Thompson/Center Arms, an S&W company acquired in 2007.
Smith & Wesson's total rifle production has increased through the years since it entered the rifle market. In the past, the company had marketed rifles and shotguns made by other manufacturers, but had not manufactured a long gun in house since World War II to fulfill a British military contract. Smith & Wesson made this entry into the long gun market because it was estimated in 2007 as a $1.1 billion market, 80% larger than the U.S. handgun market.[4][5][6][7][8][9][10]
In May 2008, Smith & Wesson introduced their first AR-15 style rifle in a new caliber, the model M&P15R, a standard AR platform rifle chambered for the Russian 5.45×39mm cartridge.[11] This was due to the availability cheap surplus Communist Bloc 5.45mm ammunition and AK-series weapons.[11] It had a 16-inch barrel, 6-position collapsible stock and a stainless-steel 30-round magazine. However, few shooters wanted an expensive AR-15 clone in a non-standard caliber that needed special magazines.[11] As a result, the model was abandoned in 2011 due to poor sales.[12]
