What gun does the NPC Knight near the Turret have? I've had a quick leaf through the Handgun page on the wiki and it doesn't look like any of them. Given what the other NPC Knights usually carry it'd probably be in the 2-3 star range.
One of the first guns I checked was the Iron Slug and it looks way different:

LOL
Looks like a magnus hybrid of some sort. Maybe it 's a retexture. NPC like to have special re-textures of standard equips.
Compared the two and they do look quite alike, though to be honest I prefer how the reskin looks.
First Rhendon's Shield and now this? Why do NPCs get all the nicest-looking gear?!
Spiral Spy- CALLAHAN with magnus texture. Now was it on purpose to add an unique feel or is it truly a (good looking) bug?
That's not an Iron Slug, it's a Callahan reskinned with the Mega Magnus texture.
Right it's a callahan (or whatever, on spiral spy it just says 'quad'), but still with regular magnus texture. Mega Magnus makes it brownish instead of gray and removes the yellow dots.
Edit: Derp
Looks like the Iron Slug though.
