The PGP has been around as long as the sport almost, whch translates into the most refined piece of paintball equipment mass produced. I've owned mine for almost a year and I never had a single ball break, CO2 leak, jammed chamber, or any malfunction whatsoever. The CO2 efficiency is great, I shoot around 35-45 decent shots from a single 12 gram. It has amazing accuracy. For instances, I was nearly 70 feet from my opponent with about a 3" by 8" target when I aimed with the little brass bead sight on top and nailed him in his arm. Best of all about this gun everyone gives you the attention of an Angel, but they don't know what lies beneath this innocent looking pump pistol.
Weaknesses:
I have nothing bad to say about it. And for you skeptics that think this has no potential or slow firing rate, just visit the stussing website.
Conclusion:
Purchase is a must. Because when your main gun takes a day off by breaking on you this gun just won't die. Also for you ammo wasting, poor marksmen, sissies you can get this gun turned into the only closed bolt semi-automatic paintball pistol. That's right a single hand shooting autococker pistol. But I use mine completely stock and it's the perfect paintball gun, always works, shoots straight, never breaks balls (including brass eagle or whatever's liing in the dirt at the field), and fits into anybody's budget.
