mosins do not have magazines in real life, they are a bolt action rifle that top loads 5 into the build in mag. Currently there is only one aftermarked stock that allows the mosin to take a detachable magazine and it just released in 2013 so is not widespread. I'm sure there will be a firearm in game further along in development that will fill the role of a long range rifle with a detachable magazine. If we are asking for any changes to mosins it should be to make them less accurate, the typical ammo available for them is not manufactured to a very stringent standard and therefore shot placement varies widely from one shot to the next when comparing them to more modern munitions. Mosins are great guns, I own 2, unless you spend the money for modern ammunition they are not capable of long range precise shooting due to variances in ballistics from one round to the next. I could live without that level of damage to my bags contents when shot, although I wouldnt mind seeing items fall out of badly damaged or ruined bags when you run.
