This thing shoots excellent!!! If you get custom work from Sam Tussing, it'll shoot as great as any stock gun out there. With VA, barrel bore honed to medium instead of small, and valve job (50 shots per 12 gram!!!), its a great gun. also get a custom 12 gram fast changer.
Weaknesses:
the stock PGP shoots terribly with large bore nelson paint, I played at a FPO and every shot was a ball break! definitely get a barrel hone, but with smaller bored paint, you'll do fine. changer is a prob as well. but can easily be fixed. and the tube cap is hard to take off and on, get a custom cap made to make you life easier when getting caught in a sweep on the field.
Conclusion:
It works beautifully, get one, they cost a bit more than a case of paint, and it will change your playing style if you play constantly with it for about 6 months. With the new PGP 2000 model, there is no more problems of the old versions.
