It can have an effect. Really you want a good hop-up and high quality barrel. Once the BB stabilizes in the barrel, extra barrel doesn't help you. Typically pistols don't have the range of other platforms, but it isn't necessarily short barrels that are the cause. A few pistols have been known to have decent range over others, but pistols are typically CQB go-tos and not effective primary's.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
