I hope you keep in mind the people that your playing with when you use something so inconsistent. Most people wouldn't want to take that risk and play with a Co2 gun in such close quarters and nobody that doesn't know the consequences should have to either. Remember that airsoft is supposed to be fun for everyone.

I would consider anybody lucky that got to play with a Co2 at Jon's. A private party is one thing where everybody knows about Co2, its completely another thing in regular play.
With that said, if somebody is looking to purchase a pistol to use in CQB why even take the risk buying Co2. The odds are against you.
