The new Sharpshooter perk is out, and with it some new weapons. I've only had limited experience with the Railgun but to me it seems like the primary and alt fire modes are pretty similar except for maybe locking on to the enemies' weak points.
What are the differences in mechanics between the two fire modes?

That exactly it. The primary fire mode has a locking mechanism you can use, but the secondary fire mode turns that off but does 2x the damage. According to the recent update:
Auto lock-on damage decreased to 375
Manual lock on damage 750
2Agreeing with john's answer, I just wanted to add that other than the double/half damage for unassisted/assisted, the trajectory is totally automatic while in assisted mode, only a really lucky lineup will penetrate other zeds (although if you line up a shot normally even though assist is on, it makes no difference)
Basically if you have the time to aim (most cases you can no scope and its fine) then always use unassisted. I am not some CSGO pro that can 180 noscope people, but with some practice i don't use aim assist or even the scope.
This is also due to the time it takes to properly lock on while scoping in assisted mode, i can fire 3 shots without scope and assist in the time it takes a person to fire 1 assisted shot at half the damage. I would recommend never using assisted mode unless its a case like Patriarch is running away
