As I have posted before, I am planning to have an STI based carry gun built. I am a big fan of the bull barrel design because of the was it moves the balance of the gun forward. However, I wonder about its impact on reliablity. I have heard arguments both ways, and want to get a more informed opinion. I have also grown used to seeing ramped barrels in my 1911's and want to know if there is any advantage or disadvantage in using them.
