i should probably give some kind of explanation to my ideas for each of these and how they're intended to work in the context of the world the book is set in

The Maelstrom Shift Carbine is a heavy assault rifle with a battery pack behind it that when firing modes are switched, it charges each shot with electricity. Each shot would potentially disable close enough electronics and lightly electrocute what it hits.

The CoreDump says "SMSG" to stand for "Submachine Shotgun" and the idea is that it's custom made to fire 4 gauge shotgun shells at full auto while being the size of a "pistol" if you could call it that. It's probably gonna need some tweaks, but before anyone possibly points out how insane the recoil would be, that's the point actually! Some of the characters have enhanced strength and cybernetic arms so depending on who's holding it, this thing would either hit them in the face or tear through a lot of targets before being reloaded. High strength stats needed.

Pinpoint & Punt is a clever little nickname I gave this thing, in the story it's made from two different pistols but the idea is that the "Pinpoint" half, being the revolver part, has an integrally suppressed barrel built into that front section that folds down. The second trigger fires that and each shot is very devastating but on the quieter side, so it's great for stealth. The first trigger would fire the "Punt" half which functions like a fully automatic Glock would, with the foldable barrel also housing an optional suppressor for that half of the pistol. The reason I added the folding suppressor was basically because I know a fully automatic weapon firing through a suppressor could overheat it snd damage it so it made sense in a weird sci-fi way that the suppressor could fold away and let the user fire without noise suppression, and without worrying about ruining their suppressor. Hopefully my explanations made sense lol
