Is the trigger of Russian M91/30 (Mosin-Nagant) single stage or two-stage?
The Mosin has a single stage trigger What you are describing is known as military creep I have owned several Mosins and SKSs all have different amounts of creep The advantage of a two stage trigger is that it relives some of the pressure needed to make that final break The heaviness of the Mosin trigger pretty much refutes any evidence of a two stage trigger
