The largest external and ergonomic difference in marker bodies is in the trigger and barrel position. Designers of expensive models attempt to position the trigger frame forward towards the center, or slightly forward of center of the body on speed-ball-oriented markers. This allows the HPA tank to be mounted in a position allowing compactness and balance without requiring any additional modifications that allow the tank to fall down and forwards. Such aftermarket "drop forwards", may create a larger gun profile, which can result in eliminations due to hopper hits. Users often modify less expensive markers to allow a similar mode of operation, albeit by sacrificing a low profile. Although this is not important in games where equipment hits are not counted, in most games, including woodsball games, hopper hits are counted as an elimination. Some markers mount the barrel farther back in the gun body to preserve a compact design, sacrificing the positioning of the trigger forward on the marker body whole paintball gun body should have to clean properly for its better response
