One of the conscious decisions I made with this product was to make guns VERY similar to one another. There are no descriptions of individual models of guns, just categories like "light pistol" or "assault rifle" or whatever.
In the movies that this game is based on, it NEVER matters what sort of gun somebody is using. All guns are pretty much the same. How much damage a gun deals seems to have more to do with how angry the person pulling the trigger is than the calibre or muzzle velocity.
My hope is that it's not boring for the same reason the movies themselves aren't boring -- because the stories are so much fun and the characters are so cool.
Gun-Fu is not by ANY stretch of the imagination any sort of reality-based model. It's meant to model the dynamics and typical situations of John Woo shoot-em-ups, NOT to present accurate portrayals of what happens when something gets hit by a round from a Colt 1911.
I hope people will find that a useful thing for a game to model, and that they're able to play fun, action-filled games with it.
