During the Russo-Turkish War of 1877-78, Russian troops armed with mostly Berdan single-shot rifles engaged Turks with Winchester repeating rifles resulting in heavy casualties. This emphasized to commanders a need to modernize the Imperial army. The Russian Main Artillery Administration undertook the task of producing a magazine-fed, multi-round weapon in 1882. After failing to adequately modify the Berdan system to meet the requirements, a "Special Commission for the testing of Magazine fed Rifles" was formed to test new designs.
Sergei
Ivanovich Mosin, a captain in the Imperial army, submitted his
"3-line" caliber (.30 cal, 7.62 mm) rifle in
1889 alongside a 3.5-line design by Léon Nagant (a Belgian) and
a 3-line design by captain Zinoviev. When trials concluded in
1891, the units which tested the rifles were split in their
decision. The main disadvantages of Nagant's rifle were the
following: more complicated mechanism, long and tiresome
procedure of disassembling (which required special instruments -
it was necessary to unscrew two screws). Mosin's rifle was
mainly criticized for lower quality of manufacture and of
materials used which resulted in a bit larger number of
stoppages. The Commission voted 14 to 10 to approve Nagant's
rifle. However, the head of the commission general Chagin
insisted on subsequent trials held under the Commission's
supervision during which Mosin's rifle showed its advantages,
leading to its selection over the Nagant.












December 5,
the German 2nd Panzer Division had advanced to within a
few kilometers of Tula, forcing the Soviets to evacuate
Tula Arms Plant. As a result, far fewer weapons were
produced there than at other Soviet factories such as
Izhevsk Mechanical Plant. Consequently, Tula proofed
weapons of World War II are considered more valuable by
collectors.

through Sweden to Finland, but after a Swedish newspaper made this fact
public, Adolf Hitler initiated a policy of silence towards Finland, as
part of improved German–Soviet relations following the signing of the
Molotov–Ribbentrop Pact.
