I would much rather use a FWB C25 Co2 than a Fas 604 any day, imagine cocking a FAS 60 plus times in comps, a good recipe for fatigue imo. You can cock a C25 just by lifting the loading tap!!

Most top grade Co2 pistols don't use capsules or bulbs, they are bulk filled & will give more shots per fill than most pcp's......150 shots plus usually.
