First gun I bought was a Sheridan P-68 SC (like a PGP, only better
). I bought it twenty years ago, still have it, and it still works. The only problem is that paint companies have shrunk their paintballs and I can't find any that won't roll out the fixed barrel. Technically, the first paintball gun I played with was a Nelspot 007, which was an utter piece of crap compared to my P-68 SC. I think the early Sheridan guns were perhaps the first paintball guns that moved paintball into a sport rather than a novelty.
