The history of one of the most successful revolver designs of all times, the Smith & Wesson's "Military And Police", began in 1899, when S&W began to manufacture its "Hand Ejector" model in .38 Long Colt caliber. In 1902, S&W introduced the .38 hand Ejector revolver in its new chambering, the .38 Special, and during the following years continued to slightly improve the design. The 38 Hand Ejector took its shape in 1915. In 1920s, Smith & Wesson renamed the 38 Hand Ejector into Military and Police model, and in 1958, after introduction of the model numbering system, S&W assigned to the Military & Police revolver a model number 10. During the century, the total numbers of the M&Ps manufactured by S&W could be estimated at rough six millions plus, give or take. This included some 1 million or so revolvers, delivered to the US Government during the WW 2, and a large numbers of revolvers, manufactured for export into British Commonwealth countries.

In general, the M&P was one of the most popular police revolvers in the USA. Some sources said, that at some time period, some 80% of ALL US Police departments were armed with M&P revolvers! These guns were also used by US Military, especially in US Air Force and US Navy. The M&P's were widely copied by numerous manufacturers in Spain, France and other countries.

Technically, all M&P revolvers are double action, swing-out cylinder revolvers. All M&P family revolvers featured similar medium sized frame (S&W nomenclature code: K-frame); All M&Ps featured dual-locked 6 chamber cylinders (one lock is manually operated by the latch, located at the left side of the frame behind the cylinder and locks the rear part of the cylinder axis; another lock is a spring-loaded one that locks the front part of the cylinder axis/ejector rod under the barrel). Standart M&Ps featured fixed front sight and fixed rear sight, in the form of the groove, cut in the top of the frame. Some target versions (sse below) featured ramp front sight with ajustable rear sights. Original material of the frame was the carbon steel, blued or parkerised; later, lightweight alluminium alloy frames and stainless teeel frames were introduced. Original barrels were from 2 to 8 1/2 inches long, of thin profile, with exposed ejector rod. Later, "heavy barrel" models were introduced. Some later models also featured barrels with upper rib and / or enclosed ejector rod.
