...Dude. That's not plausible at all. You don't seem to realize that in most SciFi, Gauss guns and railguns totally replace firearms. That's why projectile weapons are not affected by polarized hull, due to the fact that coilguns and railguns fire polarized projectiles by their very nature. I was kinda willing to ignore the fact that you said a weapon that's a relic even by modern standards is still used here, but this is getting a little ridiculous, to say that a weapon that's only getting cheaper to make and more practical as time goes on just suddenly stops being produced entirely.

If you already have everything laid out, why would you even ask for player input and say you haven't developed anything yet?
