Pros:

Quality
Shotgun Sounds

Cons:

Pipe Bomb Explosion
.VPK Doesn't work well

Conclusion:

I like this gun sound mod over all the others that were made. Don't get me wrong the others were great too but I like this one the best! :D The only problems there are is the explosion of the PB and that the .VPK doesn't work well. :|
The PB explosion just sounds too dull. It needs more oomph. :P And you already know that the .VPK has a few glitches so I'll leave that out. Neither do I know a fix. I tried using SND_rebuildaudiochace but that did nothing.
Anyway I'll give this a 9/10 because I like it so much! :3
