they don't have firing hand mag releases
AUG is behind the mag, MP5, UMP, G3 are push tabs and cannot be operated with firing hand, Saiga can't even have a mag inserted when the bolt is closed much less have drop free mags- all of these should require you to pull the mag out with your forward hand and charge the weapon manually to rechamber a round
Other notes
MP5, UMP, G3, AUG also have bolt drop back and firing hand bolt release when none do IRL, and they are all operated with the firing hand
M4 bolt release is dropped with your thumb like you have a BAD lever
Uzi fires from a closed bolt
M249 charging handle springs back forward when it requires a push
