Schematic of Model 1891 (top left) The 3-line rifle, Model 1891, its original official designation, was adopted by the Russian military in 1891. There have been several variations from the original rifle, the most common being the M1891/30 (commonly referred to as 'the 91/30' by shooters), which was a modernized design introduced in 1930.

Some details were borrowed from Nagant's design. One such detail is the attachment of the magazine spring to the magazine base plate.

In Mosin's original design the spring was not attached to the base plate and, according to the Commission, could be lost during cleaning. Another detail is the form of the that could hold five cartridges to be loaded simultaneously into the magazine.

The initial rifle proposed by Mosin lacked an interrupter, leading to numerous failures to feed. This detail was introduced in the rifle borrowing from Nagant's rifle.

Although the form of the interrupter was slightly changed, this alteration was subsequently borrowed back by the Commission for the Model 1891 Mosin–Nagant. During the modernization of 1930, the form of the interrupter was further changed, from a single piece to a two-piece design, as the part had turned out to be one of the least reliable parts of the action. Only the clip loading cartridges and the attachment of the magazine spring to the magazine base plate in subsequent models were designed by Nagant. Considering the rifle could be easily loaded without using a clip, one cartridge after another, the magazine spring attached to the magazine base plate is the only contribution of Nagant to all rifles after 1930. Nagant's legal dispute [ ] Despite the failure of Nagant's rifle, he filed a patent suit, claiming he was entitled to the sum the winner was to receive. It appeared that Nagant was the first to apply for the international patent protection over the 'interrupter', although he borrowed it from Mosin's design initially.

Mosin could not apply for a patent since he was an officer of the Russian army, and the design of the rifle was owned by the Government and had the status of a military secret. A scandal was about to burst out, with Nagant threatening he would not participate in trials held in Russia ever again and some officials proposing to expel Nagant from any further trials as he borrowed the design of the 'interrupter' after it was covered by the 'secrecy' status given in Russia of that time to military inventions and therefore violated Russian law. Taking into consideration that Nagant was one of the few producers not engaged by competitive governments and generally eager to cooperate and share experience and technologies, the Commission paid him a sum of 200,000 Russian rubles, equal to the premium that Mosin received as the winner.
