FPS isn't the only factor that determines range. There are hopup systems like TM which give you a lot of range even with their pistols firing around 300fps. I'd prefer the capacity advantage here.
Also, I hope you're not using that revolver without modification. Last I read it shot over 400fps stock. People can get hurt.
