 I don't want something that's going to have premature or non-predictable wear or failure. I also don't want something that is... I'm taking the dwell time off the gun. That dwell time is, for lack of a better word, the horsepower that's driving the gun. I want as much dwell time as I need for the gun to be as mechanically and structurally tough as I can, especially if it's something I'm going to bet my life on.
