The reason for euro guns having a largish shaft overhang is because typically the shafts are only supported at the muzzle and at the trigger. The lack of central support lets the shaft sag, so the overhanging tip is used to counteract this sag. There isn't a single correct length for overhang but it should be roughly 1/3 - 1/2 the distance between muzzle and trigger. Deviating to far from that will result in either the shaft over the barrel sagging or bowing upwards, Obviously a shaft that is bending as the power is released into it will wobble more than one that was straight as the trigger was pulled. This is why you often see guns with rails sporting shorter shafts than similar looking standard euros.
