Yeah. Railguns would cut it. Which is why the Maxim should be allowed to to damage to Cap-ships. - It's for all intents and purposes a rail-gun. I dont give a flying @#^< what the Tech description says. Its a Railgun, thus a slug Shooter (projectile weapon). Since the uranium slugs are magnetically propelled, the Maxim will have an enormous range, far beyond that of most energy weapons, despite what TrashMan says.
Also, I think that as a projectle weapon, it should have an ammo gauge. I really think that future open builds should resurrect the Maxim Ammo Counter from earlier builds.
Anyway, here's hoping that ST:R finally gives a use for the secret rail gun.
@AE, the reson they are so small, is because they are essentially Bullets, not balls of superheated plasma
