Pros:

Badass graphics
Another cool thing from the Doctor

Cons:

Last time I used it, sounded too weak
Seems like it'd be better suited to replace the regular pistols.

Conclusion:

I think its a nice pistol, just should be a bit bigger to help it FEEL like a magnum replacement, it looks too like the normal pistol.

Pros:

Beautiful textures
Awesome sounds
Sweet gun

Cons:

I tend to look for this gun more than my SPAS 12 

Conclusion:

By far my favorite shotgun retexture, just try and maybe make one similar for the pump shottie, perhaps do one of the Benelli M2 for the M4?
Overall, nothing less than what i'd expect from the good Doktor.
I just wish my compy was so slow so I could see this gun in its HD glory.

Pros:

Sweet ass texture
No more awkward M16A2
Sound's fixed
Black

Cons:

Sometimes so dark you can't see the texture

Conclusion:

I've never taken this mod off since I put it on.
