Hey guys, I got myself a Piston on launch day. It's got an awesome rate of fire, but the range kind of blows. Anyone had much luck with the Slug Ammo for medium ranges? The weapon wrecks in close range panic situations, but it's useless outside of 25m. Also, what sights do you use, if any? I'd say reflex, but honestly using any sight with a shotgun seems pointless. More often than not due to range issues, I do end up using my AC-X11 Carbine and it does pretty well. I'm going to purchase a GD-7F and get the reflex sight as an upgrade to this for medium ranges. My question is this: Am I better off using the GD-7F with a reflex sight, or just getting slug ammo for my Piston for the 100 certs?
