It's generally been agreed upon that the new weapon sounds are pretty awful (I'd actually hold that almost all the weapon sounds are terrible; when I originally played Infiltration, I just thought UT99 limited you to extraordinarily low res; imagine my surprise when I submitted some 1911 sounds and they worked just fine). Unfortunately, concensus among mutator makers is that it would be some dangerous, horrible, baby killing crime to write a mutator that allows client side sound configuration for weapon firing and reloading (personally, I'd like to see it for everything, if possible). God knows it destroyed CS and DoD and MoH and CoD and every game ever made on Quake...
