Suit YOUR Purpose
As Stated by my fellow Adult players, who are old enough to legally purchase their own guns, it is all about what you want to be able to do, if you want to plink and just screw around the house or yard with your friends then yes your "clear guns" are perfect for you needs.
If you are like those of us with "black guns" as you call them. Then you want to be able to participate in large, often outdoor enviroments where you need to be able to shoot at the player that is upwind of you and still be able to hit him or her.
But thanks for posting!
