.38 Special), a slightly elongated version of the .38 Long Colt cartridge with greater bullet weight (158 grains) and powder charge increased from 18 to 21 grains of gunpowder.
These included major modification and simplification of the internal lockwork and the addition of a locking underlug on the barrel to engage the previously free-standing ejector rod.
The S&W Model 10 military revolvers produced from 1942 to 1944 had serial numbers with a "V" prefix, and were known as the Smith & Wesson Victory Model.
It is noteworthy that early Victory Models did not always have the V prefix.
Barrels of 2.5 inches (64 mm) are also known to have been made for special contracts. With this order, the Hand Ejector Model became known as the .38 Military and Police model.
In 1899, the United States Army and Navy placed orders with Smith & Wesson for two to three thousand Model 1899 Hand Ejector revolvers chambered for the M1892 .38 Long Colt U. That same year, in response to reports from military sources serving in the Philippines on the relative ineffectiveness of the new cartridge, Smith & Wesson began offering the Military & Police in a new chambering, .38 S&W Special (a.k.a.
In production since 1899, it is a six-shot double-action revolver with fixed sights.
Over its long production run it has been available with barrel lengths of 2 in (51 mm), 3 in (76 mm), 4 in (100 mm), 5 in (130 mm), and 6 in (150 mm).
The trigger return spring is a flat leaf rather than the coil spring-powered slide used in variations dating from 1905 onwards.Most of the early M&P revolvers chambered in .38 Special appear to have been sold to the civilian market. This one left the factory in 1929 and was sent with ten others to a firm in Buenos Aires.By 1904, S&W was offering the .38 M&P with a rounded or square butt, and 4-, 5-, and 6.5-inch barrels. The hammer was added later and is in the general form of the King Gun Shop modification usually intended for the timed and rapid fire portions of the NRA course.Criminal Investigation Division agents were issued .38 caliber revolvers with two inch barrels.The Victory Model remained in use with Air National Guard tanker and transport crews as late as Operation Desert Storm in 1991.Both revolvers featured varying barrel weights and lengths—generally three and four inches with and without underlugs (shrouds).Production dates begin in 1974 for the Model 13 and end upon discontinuation in 1999. Many of the S & W Military & Police revolvers were captured and used by some of the police forces, such as the Austrian Police, during the occupation after World War II.The model has also been offered throughout the years with both the round butt and square butt, i.e., grip patterns.Beginning with the Model 10-5 series in the late 1960s, the tapered barrel and its trademark 'half moon' front sight (as shown in the illustrations on this page) were replaced by a straight bull barrel and a sloped milled ramp front sight.Late model Model 10s are capable of handling any .38 Special cartridge produced today up to and including P rounds.After a small prototype run of Model 10-6 revolvers in .357 Magnum caliber, Smith & Wesson introduced the Model 13 heavy barrel in carbon steel and then the Model 65 in stainless steel.
