For USPSA/IPSC shooting in Limited class, bull barrel STI and SVI .40's ***dominate***.
I don't shoot open, but IMO the majority of open guns use comped bull barrels or cone barrels. Bushing barrels are seldom seen on these guns.
The conventional wisdom is that bull barrels reduce muzzle flip, letting you shoot a little faster. More weight at the muzzle also makes the gun a little slower swinging and harder to stop once you get it swinging. These are subtle differences. I personally like more weight at the muzzle for the reduced flip, and have never felt that it interfered with swinging the gun. OF course, I'm not Robbie, either.
