limited cap is not gonna happen in paintball unless it's milsim..
on both sports, the guns are actually redeemed to me to be cheap..
problem with paintball is that its $10/100balls on fields, and first strike..that's a joke, $1/1ball. The normal paintballs are so inaccurate it's not even enjoyable, probably upgrade your barrel to make that somewhat workable.
I don't know about your area, but in mine..There are more paintball fields than airsoft..they all do airsoft, but less, like biweekly.
