In general most of them feel a little weak, and you can't really rely on them for damage like you can in drifter. It makes sense because ammo is much more abundant and you can hold a lot of it, but at the same time it can feel bad when things just don't die to a full magazine.
That being said, why are the Radiant SG2 and the Magrex specifically so weak? For weapons with over 30 bullets and a high fire rate, they sure do take forever to kill things - especially compared to something like the Diamond Shot, which absolutely shreds through enemies for some reason. I mean even just looking at the numbers, one weapon slowly fires 36 bullets that have a base damage of literally 2, and the other shoots 4 ~40 damage bursts. I mean seriously. the Radiant sg2 just feels so slow and weak that I would literally take the basic pistol over it every single time. Same thing with the Magrex, it just goes through ammo so fast and barely does any actual damage!
At least it's actually pretty quick and noncommittal, but still, it's rare to actually kill something without reloading, let alone more than one enemy. Even though it has a faster fire rate and walk speed, it's so weak and innacurate that it still barely qualifies as a gun.
Seriously, what's up with that?
