Shameless necro-bump, as was doing stuff again recently where this would be very useful..

Right, as usual didn't even think of that.. Obviously we'd need a way to use another soundset for subsonic ammo when suppressed.
How about additional config token into the mag class, something like onConflictSoundTypeIndex, which you could use to define soundTypeIndex used in case of magazine and muzzle device conflicting. 🤔
