A simple modification that replaces the current Frontier Justice taunt sounds with unused ones I found in the "team fortress 2 content" GCF. There were only two "smash" sounds, however, so one of the default sounds are not replaced. More info concerning that is in the readme file.
This mod replaces the old, silly, horrible, or whatever as you call it Stock Revolver sounds, with sounds I found somewhere and edited to make better.
Note: The Reload Sounds applies to all Spy Revolvers.
