MCM pistol

The Margolin or (MCM pistol) Practice Shooting Pistol (Пистолет Марголина Целевой Малокалиберный) is a .22 LR pistol primarily used for competitive target shooting in 25m Standard Pistol class under the rules of the International Shooting Sport Federation for bullseye round-target shooting at 25 m. The Margolin has been used since the 1950s, and complies with all international competition standards.

History
The pistol was designed by Mikhail Vladimirovich Margolin (1906–1975). It was produced since 1948 and made its international debut at the 36th World Shooting Championships held in 1954 at Caracas, Venezuela.

A very accurate, reliable and economically priced pistol of functional and simple design. The designer himself was blind - he was fighting in the Red Army against the bandits in the aftermath of the Russian Civil War and in April 1924 (at the age of 18) had head injury resulting in total loss of vision.

There is some criticism of the pistol's elevated plane of sight, blaming it on an incorrect notion that the designer could not aim his pistol. However, Margolin's raised plane of sight is a deliberate design feature that increased the accuracy of the pistol. The bridge that made the rear sight stationary combined with the unusually high sights allows the shooter to hold the pistol lower and  aligns barrel with the shoulder, giving the shooter an improvement in control in rapid fire competition. The high line of sight is a design feature that the Margolin's designs had in common with the famous AK-47. The AK-47, designed between 1946 and 1948, like the Margolin, had high sights which lowered the barrel, put it more in line with the shoulder, reducing muzzle climb.

The barrel, being comparatively light-weight, can be equipped with an under barrel weight for added steadiness.
