The M&P History:
The Smith & Wesson M&P (Military & Police) has always been a highly respected revolver from its introduction to today. Introduced in 1899, it became the standard by which every other medium-frame double-action revolver would be judged--as well as serving as the launching platform for one of the most influential handgun cartridges in history: the .38 S&W Special. The popularity of the M&P (aka Model 10) revolver grew so quickly that it was the most widely used police revolver in the free world. In fact, the Model 10 and M&P revolver variants have seen the longest uninterrupted run of any handgun in history, as it is still in production today.
The M&P line grew into a new brand of semi-auto handguns in 2006, and has become the biggest product launch in S&W's history. The company has been producing semi-auto handguns for more than 60 years, but it was not until 2006 that Smith & Wesson would roll out a semi-auto worthy of the M&P logo. Before embarking on the process of building a new pistol, S&W personnel conducted extensive interviews of law enforcement and military agencies, competitive shooters, and civilian gun owners. The information enabled engineers to include a number of features these varied groups thought were desirable. If you are going to build the finest modern tactical pistol, it is a good idea to get input of those who will use it.
Since, its introduction in 2006 the M&P has won more than 600 LE agency "issue weapon" contracts. (Source: S&W marketing) That is more new contracts than any other brand in that time period.
The NEW M&P semi-auto really is a worthy heir to the brand's name and reputation.
O ya best part is, it made in the USA, by S&W.
